Time measurement (CPU time, wall time)

There are two ways to measure time:

  • CPU time - the time actually spent by CPU executing method code.
  • Wall time - the real-world time elapsed between a pair of events, e.g. between method entry and method exit. If there are other threads/processes concurrently running on the system, they can affect the results.

CPU profiling

You can choose between CPU and wall time measurement in CPU sampling settings and CPU tracing settings.

By default, the classic synchronous sampling and asynchronous periodic sampling measure CPU time, and they can be configured to measure wall time instead.

Asynchronous CPU sampling always measures CPU time.

Tracing measures wall time by default and can be configured to measure CPU time instead.

Monitor profiling

Monitor profiling measures wall time for all waits and blocks.
