A PHP page that takes seconds, a request that times out under load, a cron that never finishes — slow PHP apps usually have one dominant cause.
I run a PHP performance diagnosis against your existing system: slow-query log, EXPLAIN output, profiler data and request timing. You get a short report naming the bottleneck and the cheapest fix first.
Diagnose why a PHP application is slow, no rewrite required.
Diagnosed a slow Symfony application where a single unindexed query was adding 2 seconds to every page load. Used slow-query log analysis and EXPLAIN to find the cause — a missing composite index on a frequently joined table. Fixed in under an hour.
You paste or upload slow-log/profiler output and a sample of the request flow. I trace the slowest path with profiling, confirm the cause with EXPLAIN or timing data, and return a written diagnosis with the fix order — what to change first, what to change next. One focused session.
Performance diagnosis and a written diagnosis with prioritized recommendations. Implementation is optional and quoted separately.
No. Diagnosis works from logs and profiler output you provide. Implementation, if you choose it, happens in a follow-up with the appropriate access.
Most single-request slowness cases are resolved in one focused session. Larger systems need a broader sampling pass first.
