(296% increase in site speed for UK’s leading Bioethanol Fireplaces Suppliers)

ImaginFires, a UK bio-fire brand operating on traditional Magento, struggled with poor website performance. And that was causing hurt to store conversions. The main issue was their use of a heavy and generic theme packed with unnecessary features, slowing page load times. With winter approaching, their peak season, they needed a performance-focused solution.

ImaginFires evaluated multiple options and chose the Hyvä theme for its speed optimization, and integration ecosystem. They had a core objective to achieve a lighthouse score above 80 and improve core web vitals, and the Hyva theme proved to be the best Magento performance optimization solution.

Magento Store Performance Comparison:

The table clearly demonstrates the dramatic improvement in Magento store performance after implementing the Hyvä theme.

Metric	Before Hyvä Theme	After Hyvä Theme	IMPROVEMENT
Performance Score	23	91	+296%
Accessibility	82	100	+22%
Best Practices	75	100	+33%
SEO	84	100	+19%
First Contentful Paint	6.4s	0.5s	↓ 92% faster
Time to Interactive	21.2s	0.5s	↓ 98% faster
Speed Index	11.9s	1.1s	↓ 91% faster
Largest Contentful Paint	8.6s	2.1s	↓ 76% faster
Total Blocking Time	1120ms	0ms	Eliminated
Cumulative Layout Shift	0.05	0.009	↓ 82% better

You can see that before implementing Hyvä Theme, ImaginFires’ magento store performance was weighed down by a generic theme containing unnecessary features. And that was resulting in poor performance scores and extremely slow loading speed.

Metrics like Time to Interactive (21.2s) and Speed Index (11.9s) highlighted serious usability issues, creating friction for shoppers and hurting conversions. The slow server response time and high cumulative layout shift were major concerns too.

However, when they chose to implement Hyvä Theme, their Magento store achieved near-perfect Lighthouse scores across performance, accessibility, best practices, and SEO. The performance improvements included drastically reduced load times, site interactivity in just 0.5 seconds, blocking time dropped to 0ms, and cumulative layout shift was minimized for a smooth shopping experience.

Pro Tip: Speed improvements directly impact sales. Even a 1-second faster load time can boost conversions by up to 7%.

This Magento speed before and after Hyva difference shows how Hyvä Theme not only boosts speed optimization but also strengthens SEO, accessibility, and overall conversion readiness.

Also, this Hyva theme performance case study also confirms that merchants experience better conversions after store speed optimization.

Understanding Traditional Magento Store Performance Problems

To learn how Magento store performance is impacted with and without the Hyva theme, we must understand the problem with traditional Magento. Traditional Magento themes (including the default Luma theme) suffer from several critical performance bottlenecks that affect optimal performance:

Problem 1# Heavy JavaScript Framework Dependencies

When a customer visits your Magento store, their browser must download and execute multiple JavaScript frameworks to display functional content. Traditional Magento uses heavyweight JS files that require complex JS file loading processes.

Core JS Framework Issues with traditional Magento

1. RequireJS → Loads modules sequentially instead of in parallel, creating waterfall delays where customers see blank screen during page loads.
2. KnockoutJS → Over-engineered for eCommerce needs, loads the entire framework even for simple “Add to Cart” functions.
3. jQuery → Loads a complete library for basic tasks modern browsers handle natively.

To optimize JS file loading, merchants are required to follow lengthy processes of deferred JS loading and advanced JS bundling. However, regular Magento JS bundling often falls short compared to advanced JS bundling eliminates many performance issues.

Problem 2# Inefficient CSS Architecture

Magento’s CSS Architecture creates multiple efficiency problems that result in slow page rendering and poor Magento store performance.

Just as JS files, the platform loads CSS files sequentially rather than in parallel, meaning each stylesheet must be completely downloaded and parsed before the next one begins loading. This approach ignores critical CSS principles and CSS critical path optimization.

This creates a cascade effect where five separate CSS files totaling 450KB load one after another instead of simultaneously. The platform fails to merge CSS files effectively.

Due to that, web pages suffer from heavy CSS bloat, loading styles for unused components (checkout, product comparison, even admin). As a result, only 15–25% of the CSS is actually used, wasting 75–85% of downloads.

Mobile optimization presents additional challenges due to Magento’s desktop-first approach, with mobile added later.

This leads to overlapping rules, scaled-down desktop images, and unusable hover states. So, mobile users end up downloading 2–3x more CSS than they need being the reason for poor Magento store performance.

Mobile devices users end up downloading 2–3x more CSS than they need, being the reason for poor Magento website speed.

Problem 3# Complex Rendering Pipeline

Modern websites should load content progressively, showing users valuable information immediately while additional resources load in the background. Magento’s rendering pipeline works against this principle by creating dependencies that prevent content display until all resources are available.

A single product page typically requires 40-80 separate HTTP requests to fully load.

This includes the initial HTML structure, multiple CSS and JavaScript files, numerous JavaScript files, AJAX requests for dynamic content like recommendations, individual image requests, web font downloads, and third-party service calls for analytics and widgets.

Each request creates potential delay points that can slow the entire page loads process and increase server load.

The platform also makes critical content dependent on its heavy tech stack, causing poor Magento store performance and longer load time. The system often creates render blocking resources that prevent fast loading, affecting website loading speeds and server response time.

The Hyvä Theme | Performance-First Magento Theme

Let’s understand how the Hyva theme helps with Magento 2 speed optimization by bringing in a solution for Magento store performance issues that merchants have been facing for decades.

What is the Hyvä theme?

Hyvä is a lightweight, high-performance frontend theme for Magento 2.

It aims to address performance issues associated with the default Magento Luma theme and other traditional themes by offering a simplified, modern approach to frontend development.

Hyvä uses modern frontend technologies like TailwindCSS and AlpineJS to create faster, more efficient Magento stores.

One hidden benefit of Hyvä’s modern tech stack is easier long-term maintenance. Less code and fewer dependencies mean lower Hyva theme development cost, upgrade costs, and fewer bugs slowing your store down.

Overall, the Hyva theme is “Everything your current store offers + Lightning fast page speed”.
