Microsoft xperf tool

While the data collection is running, the XPerf tools are not even loaded - the kernel itself is collecting the data. All analysis is done in post processing. Since Xperf is ETW based, sample profiling can be started and stopped at any time, without stopping or restating even a single process. You can profile anything at any time on any system. The traces are logged in a circular fashion, based on the buffer size that is set.

The basic process is this:. Once a trace is taken, you can copy it to a Windows Vista or Windows Server machine for trace decode and viewing. This browser is no longer supported. Download Microsoft Edge More info.
