Questions tagged [profiler]

A profiler is a programming tool used to track and analyse the performance of a software program.

A profiler is a programming tool to track and analyse the performance of a software program. Profilers can focus on different aspects, for example:

  • memory usage
  • cpu usage
  • the frequency and duration of function/method calls
  • resource usage

Most profilers use a process called instrumentation (adding measuring code) to gather data, but some profilers can also use sampling (polling data at specific intervals).
