Performance
Ergofix Rocket Cache
Full-page caching at the Nginx layer that serves the page before PHP ever wakes up.
Under load, page speed that depends on PHP running on every request is speed you cannot count on. Ergofix Rocket Cache moves the whole page off the hot path: Nginx answers directly from cache, PHP stays out of the request entirely, and cart and account remain live through surgical AJAX refresh. Speed stops being a plugin you hope holds and becomes a property of the architecture.
What it does
Cache at the edge of the stack
The full page is served straight from the Nginx layer, so the request is answered before the application stack is ever touched.
Near-instant TTFB for guests
Anonymous visitors and crawlers receive the page almost immediately, because their request never queues behind PHP.
Live cart and account
Personal state — cart, login, account — is refreshed surgically over AJAX on top of the cached page, so nothing dynamic goes stale.
Holds under load
Because most requests never reach PHP, traffic spikes are absorbed by the cache instead of piling onto application workers.
How it works
- 01
Serve before PHP wakes
Nginx checks its full-page cache first and returns the stored response, keeping PHP off the hot path entirely for cacheable requests.
- 02
Separate static from personal
The shared page shell is cached once for everyone, while the parts that differ per user are marked as dynamic and left out of the cached body.
- 03
Rehydrate over AJAX
Once the cached page loads, a lightweight AJAX call fills in cart and account state, so every visitor sees fast structure and correct personal data.
What you get
- Guests see the storefront almost instantly, which strengthens both conversion and crawl budget.
- Traffic peaks and campaigns are absorbed by the cache instead of overwhelming your servers.
- Cart and account stay accurate and live, with no stale personal data behind the speed.
- Performance becomes predictable and structural, not something you renegotiate every time load rises.
