Is Magento performance work right for you?

Choose this service when storefront, checkout, or admin speed is the main problem. Choose support for ongoing bugs, patches, and small changes.

A Good Fit

  • Your store is live, but slow pages, checkout delays, poor Core Web Vitals, or a slow Magento admin are holding it back.
  • You want us to find and fix what is slowing down the storefront, checkout, admin, server, database, or hosting.
  • You want before-and-after performance checks, not a general support queue.

Probably Not a Fit

  • You mainly need day-to-day support for bugs, patches, and small changes.
  • The store or release process is failing and needs rescue work before speed improvements.
  • Your main problem is stock, order, ERP, or marketplace integration rather than speed.

Performance proof

How we measure performance improvements

We measure the journeys that matter: product pages, cart, checkout, and Magento admin. Changes are checked before and after release.

Measurement baseline

Core Web Vitals and key journey timings recorded first

We record current performance across product pages, cart, and checkout before making changes.

Fix order

Slowdowns ranked by customer and sales impact

We fix the slowdowns most likely to frustrate customers or staff first.

Results check

Before/after checks on release

We check the live result after release and watch for performance regressions.

Client Result

What we did
We tightened dispatch and sync controls while improving the reliability of fulfilment decisions.
Result
Sales rebounded quickly after the main speed and order-handling problems were fixed.

Targeted Results

Typical outcomes from focused performance work

  • Faster high-intent journeys from product discovery through checkout.
  • Safer releases because performance problems are checked early.
  • Time is focused on the speed improvements most likely to help customers and sales.

When Magento speed work is the right choice

Choose this service when the store is live but slow pages, checkout, or admin are frustrating customers, staff, or search performance.

Pages Feel Sluggish

Category and product pages take 3+ seconds to load. Customers bounce before they even see your products.

Checkout Lags

The 'Place Order' button spins forever. Addresses take seconds to save. Friction kills your conversion rate.

Admin Feels Slow

Product saves, order grids, imports, and configuration changes drag. Operations lose time and release confidence drops.

Server Spikes

Traffic surges (like email blasts) crash the site or cause 503 errors because your stack can't handle concurrency.

Poor Core Web Vitals

Failing LCP (Largest Contentful Paint) or CLS (Layout Shift) scores are hurting your Google rankings.

Where We Focus

We find the specific causes of slow pages across the theme, database, caching, and hosting.

Hyvä & Frontend Performance

We improve or replace the theme to reduce heavy scripts, make pages appear sooner, and improve Core Web Vitals.

Database & Query Tuning

We find slow database queries, improve indexers, and remove unnecessary data so products and admin pages load faster.

Hosting & Caching

We improve Varnish, Redis, and OpenSearch or Elasticsearch settings so repeated requests are handled faster.

If releases are currently unstable, begin with Magento Rescue. If you need ongoing help after the speed work, pair this with Magento Support.

What We Review

What’s Included in the Review?

We check the main parts of Magento that can make the storefront, checkout, or admin slow.

  • Analyse Core Web Vitals (LCP, FID, CLS)
  • Review JS Bundling & Minification
  • Inspect Varnish & Redis Hit Rates
  • Audit Third-Party Module Impact
  • Profile Slow Database Queries
  • Check Indexer Health & Cron Schedules
  • Optimize Image Delivery (WebP/AVIF)
  • Review Server PHP Worker Limits
  • Validate CDN Configuration
How It Works

How we improve Magento speed

01

Performance Snapshot

We measure the live store to find exactly which pages and actions are slow, when it happens, and who it affects.

02

Find the Cause

We review the code, theme, database, and server logs to find whether an extension, query, image, script, or hosting setting is responsible.

03

Findings & Plan

We explain the slowdowns in plain English and provide a prioritised list of fixes ranked by customer impact and effort.

04

Fix, Test & Release

We make the fixes away from the live store, check the speed improvement, and release the changes carefully.
