Stabilising OpenCart under filter-driven load
On the live store, filter combinations and automated traffic generated large volumes of expensive requests, inflated the file cache and overloaded PHP-FPM.

Project brief
Stop repeated load from combinatorial filter URLs before PHP without disrupting normal customer navigation or valid catalog pages.
What was delivered
- separated customer and automated requests targeting OCFilter combinations
- returned an early Nginx response for unwanted traffic before PHP-FPM execution
- corrected OCFilter cache-key generation
- implemented bounded cleanup of expired cache files
- prevented concurrent cleanup processes from competing over the cache directory
- verified public pages, filters and server load after deployment
My role
Diagnosed production load, analysed OpenCart and OCFilter, implemented focused Nginx and file-cache fixes, and verified behavior against real requests.
Outcome
Combinatorial requests from automated traffic no longer pass through the full PHP stack, while file-cache cleanup now runs predictably without parallel expensive scans.
Verification
- Live website
- The production diagnostics and deployed fixes have been confirmed by the owner.
