What Our Magento Speed Optimization Services Cover
Magento Performance Audit
We measure exactly where your store loses time — slow database queries, full-page cache misses, unoptimized extensions, heavy Magento layouts, and server response — so every fix targets a real bottleneck, backed by before-and-after numbers.
Core Web Vitals Optimization
We bring your store into the green on the metrics Google ranks — LCP, INP, and CLS — fixing the loading, layout, and JavaScript issues that specifically drag Magento storefronts down.
Hyvä & Front-End Optimization
We optimize the storefront layer — including Hyvä theme migrations and front-end rebuilds that shed Magento's heavy legacy frontend for dramatically faster page loads, without losing functionality.
Cache, Indexing & Back-End
We tune what page-level fixes can't reach — full-page cache and Redis configuration, indexer performance, Elasticsearch, and database optimization — the deeper work that keeps a Magento store fast under load.
Checkout & Catalog Speed
We focus optimization where it converts — product pages, catalog browsing, and checkout — because on a store, these are the pages where slow load times cost you sales directly.
Magento Stores We Optimize
High-Catalog Stores
We optimize Magento stores with large catalogs — thousands of SKUs, heavy filtering, and complex category pages — where indexing, search, and catalog rendering are the real speed bottlenecks.
High-Traffic & Peak Sales
We optimize stores that face traffic spikes — sales events, campaigns, seasonal peaks — tuning caching, infrastructure, and checkout so the store stays fast and stable when it matters most.
B2B & Complex Commerce
We optimize B2B and complex Magento stores — custom pricing, large orders, and integrations — where performance has to hold up under logic far heavier than a simple storefront.
Hyvä & Headless Builds
We optimize modern Magento storefronts — Hyvä themes and headless setups — squeezing maximum speed from the front-end architecture built for performance.

Having SCIMUS as Your Partner
Jay Oyakawa
CEO at DermPRO
Working with the SCIMUS team has been a great experience. What began as a small testing engagement has evolved into a long-term partnership over the past 8 years. We now have a dedicated team that has grown and matured with us over time. They are proactive, detail-oriented, and understand our industry well. SCIMUS consistently delivers scalable, cost-effective solutions and operates with minimal oversight. We consider them a true extension of our internal team.
Vladimiras Lekecinskas
Director, Boutique Consulting Firm
The client's long-standing partnership with Scimus has improved their web app performance scores and their ability to deploy fully functional modules. This success has also been helped, in part, by the team's great organizational culture and high regard for a balanced distribution of duties.
Brent Kell
CEO @ Valley Immediate Care
We had been managing insurance verification manually for years, which was slow and time-consuming. The SCIMUS team automated the process with their MedOps solution. Insurance details are now verified instantly, without manual follow-ups. They were highly professional, quick to respond, and communicated clearly throughout the process. The result is better workflows, fewer errors, and more time for patient care.
Sergii Vinnikov
VP of Infrastructure, Apporto
SCIMUS is able to deliver scalable solutions within timeframes, much to the client's delight. The team is highly responsive and coordinated, and internal stakeholders are particularly impressed with the service provider's creative expertise.
Pavel Lagutin
VP of Product, BitTorrent
SCIMUS has shortened the company’s six-month recruitment process into a two-month transaction. They source highly qualified candidates who seamlessly integrate with internal structures and teams, and they demonstrate an extensive understanding of the job market and the skills required by the company.
Johan Aussenac
CEO @WeTransact
The SCIMUS team did an excellent job. The final result looks great, and the entire process was handled with strong communication and attention to detail. We appreciated how responsive and easy to work with the team was, and we’re looking forward to working together again.
Olha Shvedova
COO | Media Network | ENKO
The Scimus team supported us in building our website and is now helping us develop a platform for artists to promote their tracks. They are highly responsive, attentive to detail, and great to work with. The team understands our goals and translates them into practical, scalable solutions. We’re very satisfied with the collaboration and see Scimus as a reliable long-term partner.

Frequently Asked Questions
Why is my Magento store so slow?
Magento is powerful but heavy — slow performance usually comes from full-page cache misconfiguration, unoptimized or conflicting extensions, a bloated database, slow indexers, an unoptimized Luma frontend, or under-provisioned servers. We identify which of these is actually costing you speed, then fix the ones that matter most.
What's the difference between optimizing Magento and just upgrading hosting?
Better hosting helps, but it treats the symptom, not the cause — a poorly optimized Magento store will be slow on expensive servers too. Real optimization fixes the cache, database, indexers, extensions, and frontend so your store runs fast on reasonable infrastructure, rather than throwing money at hardware.
Can migrating to Hyvä make my store faster?
Often dramatically. Magento's default Luma frontend carries heavy legacy JavaScript that's hard to optimize; Hyvä replaces it with a lean, modern frontend built for speed — frequently the single biggest Core Web Vitals improvement available to a Magento store. We assess whether it's the right move for you and handle the migration if it is.
Do you work with Adobe Commerce as well as open-source Magento?
Yes — the performance engineering is the same across Adobe Commerce (Magento Commerce) and Magento Open Source. Whether you're on the enterprise edition or the community one, the bottlenecks and the fixes are largely the same.
Will optimization affect my live store or checkout?
Not the way we do it — we work on staging and test thoroughly before anything touches production, so optimization never risks your live store or interrupts sales. On a revenue-generating store, that caution isn't optional.
How much faster will my store get?
It depends where you're starting — a store with cache issues and a heavy Luma frontend sees dramatic gains, while an already-tuned store sees more targeted improvements. That's why we start with an audit and benchmark: we show you the realistic improvement before committing, and prove the result with before-and-after numbers.
