# Shopware performance - measured, optimised, documented.

We push your Core Web Vitals into the green - with our own plugins for cache, CDN and update orchestration.

What we measure

## Six metrics - *data-driven*.

Optimising performance without measuring is superstition. We use Lighthouse, WebPageTest, real-user monitoring and the Shopware profiler - and deliver numbers, not claims.

Time to First Byte

### Origin server response time

If the server takes long to answer, nothing else matters. We tune PHP OpCache, Redis sessions, database indexes.

Largest Contentful Paint

### Hero image or headline

The biggest visible element must arrive in under 2.5 seconds. Preload, critical CSS, fast fonts - we make it as fast as possible.

Cumulative Layout Shift

### Jumping content

Nothing is more annoying than a button moving when you click. We reserve image space, lock font swaps, keep layout stable.

Interaction-to-Next-Paint

### Reaction to clicks

If a filter click takes 800 ms, users bail. We unload the main thread, split JS bundles, optimise event handlers.

Cache strategy

### HTTP, reverse proxy, app

HTTP caching, reverse proxy (Varnish/Nginx FastCGI), Shopware page cache, Redis for sessions. Configure every layer correctly.

Image delivery

### Format, size, lazy load

WebP instead of JPEG, correct image sizes instead of 4K originals, native lazy load below the fold. Images are usually the biggest lever.

Our tools

## Three *own plugins* as the foundation.

Performance optimisation with tools we built ourselves and refined across dozens of projects.

Three own plugins · ready to deploy

### We have built three performance plugins ourselves, drawn from real customer projects.

Instead of starting from scratch each time, we lean on what has proven itself - Cache Warmer for hot caches, CDN for global delivery, Update Manager for zero-downtime updates. All three are in the Shopware Store.

Cache Warmer

### Cache before the first visitor

Keeps your shop hot: scheduled warming of all caches per sales channel and customer group. [More on Cache Warmer](https://stoneandwater.online/en/cache-warmer.html)

Shopware CDN

### Global delivery

Images, videos, theme assets via CDN - Europe-wide edge nodes, automatic URL rewriting. [More on CDN](https://stoneandwater.online/en/shopware-cdn.html)

Update Manager

### Updates without downtime

Plugin and core updates orchestrated without cache collapse - every version is tested first. [More on Update Manager](https://stoneandwater.online/en/update-manager.html)

How we proceed

## Six steps - from measuring to *ongoing care*.

Performance tuning is detail work. We go through systematically and document every step - so improvements still hold up six months later.

- 01
**Performance audit** Lighthouse measurement on desktop & mobile, real-user-monitoring analysis, Shopware profiler logs. Result: clear lever ranking by impact.

- 02
**Quick wins** What can be done in 1-3 days: image compression, lazy load, critical CSS, cache TTL tuning. Often 20-40 % Lighthouse improvement on day one.

- 03
**Cache strategy** HTTP headers, reverse proxy, Shopware page cache properly tiered. Schedule Cache Warmer, configure customer-group-specific cache keys.

- 04
**Asset optimisation** Deliver images via CDN, WebP conversion, self-hosted fonts with preload, JS bundle splitting. Optimise theme build.

- 05
**Backend tuning** PHP OpCache, MySQL indexes, identify slow queries, Redis for sessions. Drive down server response time.

- 06
**Monitoring & care** Performance budgets in CI, regular Lighthouse checks, RUM data observation. Performance is not a project, it is a state.

Service models

## Three *tiers of collaboration*.

From audit to deep optimisation - including our own plugins with no licence surcharge. Actual effort follows from the audit findings.

Performance audit

### Measurement & lever ranking

Full measurement of your shop with action list and impact estimate. Result: a concrete lever ranking that every optimisation can build on.

Quick-win sprint

### Compact optimisation sprint

The most obvious performance killers cleared in one sprint - typically 30-60 % Lighthouse improvement within days.

Deep optimisation

### Full programme

Cache, CDN, backend, frontend, monitoring in one coherent programme. Includes plugin installation and configuration - effort depends on the starting state.

**Request performance audit** Send us your shop URL - we run a first Lighthouse check and tell you where the biggest levers are.
