Make Magento fast — at the root cause, not with a plugin
Full-stack performance work that takes Magento stores from 8-second loads to sub-2 seconds and passes Core Web Vitals. From the team that built Pulsar, our Magento monitoring product.
What is Magento speed optimization?
Magento speed optimization is the work of making a Magento store load and respond faster — improving server response time (TTFB), Core Web Vitals (LCP, CLS, INP), and the time it takes a shopper to see and interact with a page. Magento is a large, database-heavy application, so real speed work spans the whole stack: database, caching, PHP, and the frontend.
Speed isn't cosmetic. Google uses Core Web Vitals as a ranking signal, and every additional second of load time measurably reduces conversion. A store that takes eight seconds to load is leaking both rankings and revenue — and 'speed' plugins that promise a one-click fix rarely touch the database queries and caching strategy where the real time goes.
Why most Magento stores are slow
Slow Magento is almost never one thing. It's un-tuned database queries, a cache layer that isn't configured for the catalog size, Varnish not sitting in front of the app, Redis under-provisioned, PHP-FPM starved of workers, unoptimised images, and a Luma theme shipping more JavaScript than the page needs. A 'speed optimisation' extension can't see most of that — it bolts onto the frontend and leaves the expensive backend work untouched.
How we actually make it fast
We profile first. Database query analysis, full-page-cache and Varnish/Redis review, PHP-FPM and OPcache tuning, and a frontend audit of critical CSS, JavaScript, and image delivery tell us where the seconds actually are. Then we fix the root causes in priority order and measure the result against real Core Web Vitals — not a synthetic lab score. Because we built Pulsar, our Magento monitoring product, we can also keep watching performance after the engagement, so regressions surface before customers feel them.
What a speed engagement covers
Full-stack work that fixes the cause of slow Magento, not just the symptoms.
Performance audit
Full-stack profiling — database, caching, PHP, and frontend — to find where the seconds actually go, with a prioritised fix list.
Database & query tuning
Slow-query analysis, indexing, and schema fixes for the catalog and checkout paths that dominate response time.
Caching strategy
Full Page Cache, Varnish, and Redis configured and right-sized for your catalog and traffic — not left on defaults.
PHP & infrastructure
PHP-FPM pool sizing, OPcache, and server-level tuning so the app has the headroom it needs at peak.
Frontend & Core Web Vitals
Critical CSS, JavaScript trimming, image and font delivery, and — where it fits — a move to Hyvä or headless.
Monitoring with Pulsar
Optional ongoing performance and uptime monitoring so regressions are caught the moment they appear.
How a speed engagement runs
How it works
Profile
We measure the full stack — TTFB, database, cache hit rates, PHP, and Core Web Vitals — to find the real bottlenecks rather than guessing.
Fix the backend
Database queries, caching, Varnish/Redis, and PHP-FPM tuned in priority order — where most of the response time usually hides.
Fix the frontend
Critical CSS, JavaScript trimming, image and font delivery optimised; Hyvä or headless where the theme is the bottleneck.
Verify Core Web Vitals
We re-measure against real field data, not just a lab score, and confirm LCP, CLS, and INP pass.
Monitor
Optionally wire up Pulsar so performance regressions surface before they cost you rankings or conversions.
Shipping Magento since the Magento 1 era — first as SoftCommerce, now as Byte8
We're a London-based commerce engineering studio that has been building and maintaining Magento stores across the Magento 1 and Magento 2 eras. The same team now ships the Pulsar, Orbit, Horizon, and Cargoman products — tools born from the real stores we run.
The Tile Depot → CTD Group
Built and maintained the Magento storefront for The Tile Depot's London branches for years — through to the business being acquired by CTD Group.
Barclays ePDQ
Appointed by Barclays to build the ePDQ payment gateway extension for Magento — bank-grade payment integration to their specification.
PlentyMarkets → PlentyONE
Appointed by PlentyMarkets (now PlentyONE) to build the official Magento 2 / Adobe Commerce ERP integration — still shipped today as the Byte8 PlentyONE Connector.
UK & EU merchants
Haka Kunz (Germany), Dampfi (Switzerland), Wills Vegan Shoes (London), and many more stores built and run across the UK and Europe.
