WooCommerce performance Case study
A2 MU Fullpage Microcache
A2 MU Fullpage Microcache 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
Product detail pages needed lower TTFB without unsafe caching of carts, logged-in sessions or checkout states.
What I delivered
- Guest-only disk-based HTML microcache for PDP and shop paths.
- Invalidation rules tied to product updates, Elementor changes and commerce events.
- A safer cache boundary around anonymous product browsing.
Technical approach
- Excluded personalized and transactional states from microcache.
- Kept invalidation explicit so stale product pages could be controlled.
- Measured the PDP path before and after release.
Result and evidence
Product detail page TTFB was reduced from approximately 2.3s to 0.9s in the measured production path.
Commercial value
The work improved the buyer-facing experience while preserving the safety boundaries a WooCommerce store needs.
Delivery notes
My role was to define the safe boundary, connect the fix to daily store operations and keep A2 MU Fullpage Microcache 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.
