John is planning to test the performance of one of the Windows 7 clients in the office by using XPerf.exe. He starts a trace with BASE Kernel Group and cswitch Kernel Flag. He now wants to stop the trace and save it in a file called selftrace.etl. Which of the following commands should he use?
  1. xperf -i selftrace.etl
  2. xperf -merge selftrace.etl kernel.etl
  3. xperf -d selftrace.etl
  4. xperf -i selftrace.etl -a tracestats -detail
Explanation
Answer - C - John should use the xperf -d selftrace.etl command to stop the trace and save it in a file called selftrace.etl.

Key Takeaway: XPerf uses Event Tracing for Windows and is very low overhead, requiring only about 1500-2000 clock cycles per log. While the data collection is running, the XPerf tools are not loaded. The kernel collects the data.
