Speed problems are usually system problems.
Performance work for sites where caching alone is not enough. I investigate the theme, plugins, database, hosting, third-party scripts and application behaviour behind the slowdown.

WordPress performance optimization starts with measurement
First, we identify the pages and journeys that feel slow. A product listing, search result and checkout can have different bottlenecks. I review field data where it exists, then use repeatable tests to understand server response, rendering, scripts and database behaviour.
The review can include hosting limits, plugin queries, external requests, images, fonts and caching rules. Changes are prioritised by their likely effect on the real user journey. Adding another cache layer is useful only when it addresses the cause.
WordPress performance optimization includes regression checks. A faster page is not a useful result if account screens, cart state or checkout behaviour break. The handover explains what changed, how it was measured and which constraints remain.
- A baseline for the affected journeys
- A prioritised list of causes and changes
- Checks for cache and commerce correctness
- Before-and-after evidence within the agreed test conditions
The outcome is a faster system and a clearer technical direction.
The first step identifies the highest-impact causes, distinguishes quick improvements from architectural work and avoids changes that merely move the problem elsewhere.
