Your eCommerce store is not a passive vehicle; it's a dynamic, high-performance engine.
Slow code and poor user experience are costing you horsepower and revenue.
This is the blueprint to re-engineering your Magento
and Hyvä store, tuning it
for unstoppable growth through foundational tuning and innovation.
Pressed for time? Here are the core specs of the Innovation Engine:
Welcome to the engine room. Your guided tour is about to begin.
Use this diagnostic panel to navigate the high-performance Magento & Hyvä systems we engineer.
In the hyper-competitive landscape of modern e-commerce, it is tempting to view a
digital storefront as a simple vehicle.
This perspective, however, is dangerously incomplete.
An e-commerce store is not a passive vessel; it is a dynamic, complex,
high-performance engine. Traffic is its fuel, the platform is its engine block, and
conversions are the raw horsepower that drives your business forward.
When this engine is perfectly tuned, it operates with breathtaking efficiency.
But when it's neglected, it sputters, leaks fuel, and costs you real, tangible revenue.
The conversation around website performance has fundamentally shifted.
User patience has evaporated, and Google has codified this preference into a business rule with its emphasis on
Web Vitals
as a direct ranking factor.
The data paints a stark picture of this new reality:
A 1-second delay in page load time can reduce conversions by 7%. For a store generating €100,000 in monthly revenue, this translates into a potential loss of €84,000 per year.
As page load time increases from 1 to 3 seconds, the probability of a user bouncing increases by 32%.
A sluggish, unresponsive site is subconsciously interpreted as a reflection of a sluggish, untrustworthy company.
Research by Google and Deloitte shows that a mere 0.1-second improvement in site speed can increase retail conversions by 8.4% and boost the average order value by 9.2%.
This guide is the master schematic for the Innovation Engine - the high-tech power plant at
the heart of the Magento Metropolis
and the advanced propulsion system for the Hyväverse. It is the active, foundational power source we engineer for every
world-class e-commerce machine we build.
As a Hyvä Gold Partner, Technology Partner, and active Hyvä
Core Contributor, we at JaJuMa don't just follow best practices; we define them.
Our team of engineers has blueprinted, built, and fine-tuned the
most powerful performance engines in the
Magento ecosystem.
This guide is our schematic. Use it to understand, diagnose, and upgrade your own engine of commerce.
Before we can install warp drives and fuel injectors, we must ensure the engine block itself is perfectly machined and balanced.
The most advanced frontend optimizations will fail if they're bolted onto a cracked or inefficient foundation.
This section covers the critical, "tool-less" aspects of performance that rely on expert architectural tuning.
Your server stack is the chassis of your engine.
A modern, well-tuned environment running the latest stable versions of PHP and Nginx is the bare minimum.
The real power, however, comes from the fuel system: your Full Page Cache (FPC).
For any serious Magento store, this means Varnish Cache.
Varnish acts as a powerful reverse proxy, serving cached copies of your pages directly from memory and completely bypassing the Magento application on most requests. When a page is served from Varnish, the Time to First Byte (TTFB) can be reduced by orders of magnitude, providing a lightning-fast experience for your visitors.
Is your foundation solid?
Our Magento & Hyvä Performance Optimization service starts with a deep dive into your server and caching configuration.
If the server is the chassis, the database is the fuel line.
Clogs and bottlenecks here will starve the entire engine of power. At its core,
Magento uses a flexible but complex data model known as Entity-Attribute-Value (EAV), which can lead to slow and resource-intensive queries.
Other common issues include unoptimized indexes and bloated log tables that accumulate over time.
Many agencies overlook the impact of Magento's EAV database structure on category and search pages.
A single product with 20 attributes can trigger over 50 database queries.
Our database audits specifically target these EAV-related inefficiencies,
often leading to dramatic performance gains that generic tuning scripts miss.
Database bottlenecks are notoriously hard to diagnose. Our engineers use advanced profiling to find and fix them.
The final piece of the foundation is the internal wiring:
Your codebase and third-party extensions.
A single poorly coded module can act like an electrical short, introducing conflicts, running dozens of unnecessary database queries, and injecting render-blocking JavaScript.
The Magento ecosystem's
greatest strength its extensibility can also be its greatest performance weakness.
That's why a rigorous code audit process is not optional; it's a critical part of maintaining a high-performance engine.
Third-party extensions are a leading cause of Magento performance issues.
Our service includes a rigorous code audit to ensure every component is optimized for speed.
For years, Magento's default Luma frontend was
a known performance bottleneck.
Migrating to Hyvä Themes is like switching from regular gasoline to high-octane racing fuel.
By completely rebuilding the frontend with a modern, lightweight stack (Alpine.js and Tailwind CSS),
Hyvä delivers a dramatic and immediate boost in power and efficiency.
This translates directly into world-class performance, with Hyvä stores commonly achieving "green" Core Web Vitals and Google Lighthouse scores in the 90-100 range - a feat nearly impossible with a standard Luma theme.
| Metric | Legacy Magento (Luma) | Modern Magento (Hyvä) | The "Engine" Analogy |
|---|---|---|---|
| Core Technology | RequireJS, Knockout.js | Alpine.js, Tailwind CSS | Heavy parts vs. lightweight components |
| Avg. Lighthouse Score | 30-50 (often lower) | 90-100 | Sputtering engine vs. tuned machine |
| Development Time | Baseline | 30-50% faster | Faster assembly & easier maintenance |

Every modern engine has an on-board diagnostic (OBD) system. For your eCommerce engine,
that system is Google's Core Web Vitals (CWV).
Mastering CWV is essential for both user satisfaction and SEO success, as Google uses them as a direct ranking factor.
Wondering how your engine measures up?
Measure your performance and calculate the real-world financial impact of your current page speed.
A high-performance engine isn't just about quality parts;
it's about the master engineer's touch.
Peak performance is achieved through a holistic, full-stack tuning process where every component -
from the server infrastructure to the frontend code -
is meticulously optimized to work in perfect harmony.
This is our blueprint for transforming a standard Magento store into a finely tuned powerhouse.
The backend is the engine block
The core powerhouse where data is processed.
Its efficiency dictates the entire system's capacity.

This is a tour of our specialized toolkit.
PIONEERED BY JAJUMA // 2025
Lab data from tools like PageSpeed Insights is the factory floor.
Without real-world data from the racetrack, you're tuning blind, optimizing
for a perfect scenario that your real customers may never experience.
Real User Monitoring (RUM) is the racetrack.
It captures performance data from real users on your site.
To provide this essential telemetry, we engineered the
first and only native RUM tool for Magento.
Our RUM extension is the ECU for your Innovation Engine.
It collects the
"field data" that Google uses to calculate your Core Web Vitals assessment,
showing you the real-world experience of your customers and uncovering bottlenecks
that lab tests miss.
This allows us to make optimization decisions based on empirical evidence, not just theory.
RUM moves you from "I think the site is slow" to
"I know exactly which pages are slow, for which users, and why."
It provides the concrete data needed to justify performance investments,
prove their ROI, and focus your budget on the optimizations that will
have the greatest impact on your revenue.
A key challenge with RUM is avoiding data noise.
Our extension intelligently filters out traffic from bots and irrelevant user agents.
Furthermore, it aggregates data not just by page type, but by specific URL patterns,
allowing us to differentiate the performance of a high-traffic category page
from a low-traffic one - a level of granularity essential for precise tuning.

PIONEERED BY JAJUMA // 2018 & 2021
In eCommerce, images are the fuel, often accounting for the largest portion
of a page's weight.
Unoptimized images flood the network,
bogging down the engine and delaying the crucial Largest Contentful Paint (LCP).
Our extension intelligently detects browser support and serves the best
possible format using the <picture> tag, ensuring universal compatibility.
We were the first to offer fully automated AVIF support for Magento
in 2021, continuing our history of innovation that began with the
first WebP solution in 2018.
Smaller image files mean faster page loads, especially on mobile.
This directly reduces bounce rates, dramatically improves your
LCP score
for better SEO rankings, and creates a smoother, more professional user experience
that builds trust and encourages conversion.
A truly 'ultimate' image solution goes beyond simple compression.
Many tools fall short by failing to serve next-gen AVIF images,
neglecting to generate responsive srcset attributes for
high-resolution Retina displays, or ignoring crucial
SEO aspects like meaningful file names.
Our extension was engineered to address this entire ecosystem,
ensuring not just the smallest file size, but also pixel-perfect rendering
on every device and optimized discoverability for search engines.

PIONEERED BY JAJUMA // 2020
A browser discovers resources like images and fonts as it reads the HTML,
which can delay the download of critical "above-the-fold" content.
This disordered fuel flow means the engine can't start rendering
the most important parts of the page first.
Our Preload Critical Assets extension acts as a smart fuel injector.
It uses
resource hints like <link rel="preload"> to tell
the browser which assets are vital for the initial view,
ensuring they are fetched with high priority.
The extension allows injecting preload tags into the HTML <head> for
LCP image, critical fonts, or key CSS files,
instructing the browser to download these assets immediately,
often in parallel with other resources, so they are ready the moment they are needed.
By preloading the LCP image and critical fonts, you directly improve your LCP score and reduce Cumulative Layout Shift (CLS). This makes the page feel faster and more stable for the user, creating a better first impression that reduces bounce rates.
Over-preloading is a common mistake that can actually harm performance
by creating network congestion.
Our extension avoids this by providing granular controls,
allowing merchants to specify exactly which resources to preload
on a per-page-type basis, ensuring only the most critical assets are prioritized.

Without a perfectly timed spark, an engine will sputter.
In web performance, the "start to render" is that spark.
By default, a browser must download all CSS files before rendering any pixels,
a major bottleneck known as "render-blocking resources."
Our Hyvä Inline CSS extension is a precision ignition system.
It automatically extracts the exact CSS needed to render the page and
places it directly in the HTML, avoiding the downsides of Critical CSS,
while providing an immediate spark for the browser
to start painting the page.
The extension analyzes each unique URL on your site and generates a specific inline CSS file for it.
This file contains only the styles required for each page.
Meaning the CSS doesn't block the initial page render, dramatically improving the perceived load time, FCP and LCP.
A fast first render is crucial for making a good first impression.
This optimization dramatically improves the FCP and LCP score and perceived performance,
which reduces bounce rates and tells both users and Google that your site is fast and reliable,
directly impacting SEO and user trust.
Automating critical CSS
for a dynamic platform like Magento is notoriously complex.
A rule that works for a simple category page might break on a page with layered navigation
filters.
Our solution is the only one that generates a unique inline CSS file for every single URL,
ensuring pixel-perfect rendering without the manual overhead or risk
of visual glitches common with page-type-based approaches.

The most advanced engines don't just react; they anticipate.
Our Perceived Performance Suite combines
three cutting-edge technologies to make your site feel unbelievably fast and responsive
by optimizing for future navigations.
PIONEERED BY JAJUMA // 2023
Navigating back and forth through a site's history often involves frustrating reloads, forcing the browser to rebuild pages from scratch and disrupting the user journey.
The bfcache is a browser's warp drive.
It stores a complete, interactive snapshot of a page in memory.
When a user clicks "back," the page is restored instantly, eliminating the wait.
The bfcache is a
powerful browser optimization that stores a complete
snapshot of a page - including its JavaScript state - in memory.
When a user hits "back" or "forward," the page is restored instantly
from memory instead of being re-requested from the server.
Given that 1 in 10 navigations on desktop and 1 in 5 on mobile are
back/forward actions, this is a massively high-impact optimization.
Instant back/forward navigation creates a seamless, app-like experience.
It keeps users in the flow, encourages product exploration,
and significantly reduces frustration, leading to longer session times
and a higher likelihood of conversion.
A common pitfall when implementing bfcache in Magento is forgetting to exclude dynamic
blocks like the minicart.
Our extension not only handles this automatically but also uses a
pageshow event to refresh the cart summary upon user interaction after a restore,
as well as further safguads ensuring data accuracy without compromising the initial performance gain.

PIONEERED BY JAJUMA // 2024
A standard browser is reactive;
it only starts loading a page after a user has clicked a link.
This inherent delay is a fundamental barrier to a truly instant experience.
Our Smart Speculation Rules extension acts as a predictive navigation computer, pre-loading a user's likely destination before they even click, making the subsequent navigation feel instantaneous.
We've engineered the first and only predictive and dynamic Speculation Rules API implementation for Magento.
This modern browser
Speculation Rules API allows us to give the browser
powerful hints to either prefetch (download the HTML) or
prerender (download and render the entire page in a hidden tab)
based on where a user is likely to navigate next.
When the user clicks the link, the page is already prepared,
making the transition appear instant.
By making the user journey feel seamless and instant,
you remove friction at critical points.
This encourages deeper site exploration, reduces drop-off between pages,
and creates a "wow" factor that enhances brand perception and boosts conversion rates.
Naive preloading can waste bandwidth.
Our extension is the first and only one for Magento that allows for dynamic,
& predictive data-driven speculation. Merchants can configure rules based on URL patterns,
CSS selectors, and page types, ensuring that only the most likely next pages
are pre-rendered, maximizing impact while conserving resources.

Even on a fast connection, there's always a delay between clicking a link and the server responding. This server think-time, or Time-to-First-Byte (TTFB), can make a site feel sluggish.
Our Page Preload extension acts like an afterburner.
As a user hovers over a link - signaling their intent to click - the extension
uses that split-second to prefetch the destination page in the background.
This lightweight tool works in the background, prefetching links that are
in the viewport or that the user hovers over.
When the user clicks, the page's HTML is already in the browser's cache,
dramatically reducing or even eliminating the Time-to-First-Byte (TTFB)
and making the site feel incredibly responsive.
This technique significantly improves the perceived speed of
navigating through your store.
The near-instant feedback after a click makes the entire site feel
more responsive and fluid, reducing user frustration and
keeping them engaged in the shopping journey.
A key concern with preloading is triggering unwanted actions,
like adding a product to the cart on hover.
Our extension is intelligently configured to ignore links with specific
parameters (like ?add-to-cart=) and non-navigational JavaScript actions.
It also includes a "blacklist" feature, giving merchants full control over
which links are eligible for preloading.

The ultimate measure of an engine's success isn't the technical specifications on a sheet,
but its real-world performance on the track.
Similarly, the success of an Innovation Engine is not measured in Lighthouse scores alone,
but in the tangible business metrics that drive growth:
conversion rates, average order value, and return on investment.
Here are the real-world performance gains our clients have achieved on the JaJuMa dyno.
It is crucial to connect the dots between technical optimizations and financial outcomes.
The causal chain is clear and direct:
An improved LCP leads to a lower bounce rate.
A lower bounce rate means higher user engagement.
Higher engagement directly correlates with an increased Conversion Rate.
A faster, more stable site (good INP and CLS) builds trust,
leading to a higher Average Order Value and increased customer lifetime value.
Challenge: A merchant's legacy Luma store was suffering from severe server instability and slow mobile speeds, causing it to fail Core Web Vitals and lose visibility and sales.
