Extension:PerformanceMonitor

The PerformanceMonitor extension profiles the work of PHP functions and methods on your server. These "profiles" (i.e. logfiles) are stored as Json-Trees in the file system. After profiling you can use the Special Page Special:PerformanceMonitor to visualise the results as diagrams.
