A free open source tool to analyze PHP opcode caches and optimize performance, helping identify bottlenecks in WinCacheGrind.
WinCacheGrind is a free, open source cache profiling tool designed specifically for PHP applications running on Windows servers. It provides visualizations and metrics to help analyze the performance of PHP opcode caches such as WinCache, XCache and APC.
By profiling the activity of the cache, WinCacheGrind can help identify bottlenecks and opportunities for optimization. For example, it can detect poorly cached code paths that lead to excessive file I/O or increased CPU usage.
Some of the key metrics provided by WinCacheGrind include hit rate, memory usage, cache entry lifespan, and more. The tool generates callgraph visualizations to highlight frequent cache misses and slow code paths.
As an open source tool, WinCacheGrind benefits from contributions of the developer community. It works well for optimizing PHP apps on all versions of Windows. With proactive cache profiling, sites can achieve faster response times and lower resource utilization.
