WooCommerce performance Case study
A2 Fast Archive Filters
A2 Fast Archive Filters documents a real commerce-platform constraint and the work delivered around it. The page is written for reviewers who need the practical story: what was wrong, what changed and why it mattered in daily operations.
The business problem
Archive filtering was one of the expensive buyer-facing paths. The goal was to make product discovery faster while keeping SEO-sensitive archive pages safe and preserving a server-rendered fallback.
What I delivered
- Modal-based dependent filters with AJAX responses and safe fallback rendering.
- Smart price buckets and cache versioning for heavy catalogue views.
- A measured improvement from about 5.2s p95 to about 1.7s p95 in the production archive path.
Technical approach
- Separated the expensive filter path from the rest of the page lifecycle.
- Used transients and explicit invalidation instead of hiding the problem behind broad page caching.
- Kept crawlable archive behaviour intact while improving interaction speed.
Result and evidence
Archive p95 improved from approximately 5.2s to 1.7s in the measured production path.
Commercial value
The project made product browsing faster and reduced server pressure without turning category pages into a risky client-only experience.
Delivery notes
My role was to define the safe boundary, connect the fix to daily store operations and keep A2 Fast Archive Filters maintainable after release.
- Defined the safe boundary before changing behaviour.
- Kept the implementation understandable for future maintenance.
- Connected the technical work to an outcome the team could use.

}What this project shows
The project made product browsing faster and reduced server pressure without turning category pages into a risky client-only experience.
For an employer or client, A2 Fast Archive Filters shows how I approach production work: isolate the constraint, choose the smallest maintainable system and prove the result without adding avoidable operational risk.
