Special Command—CPU Time for Each Thread with !runaway

  • Article

This is one of my favorite commands! !runaway displays information about the CPU time consumed by each thread in User Mode and Kernel Mode.

It is one of those commands you run when you think the application is hung with low or high CPU or has some kind of performance issue.

 

Parameters:

Bit 0 (0x1)

Causes the debugger to show the amount of user time consumed by each thread.

Bit 1 (0x2)

Causes the debugger to show the amount of kernel time consumed by each thread.

Bit 2 (0x4)

Causes the debugger to show the amount of time that has elapsed since each thread was created.

The output is sorted from the thread consuming the most CPU time to the thread consuming the least CPU time.

Example of displaying just the User Time for each thread (no parameters does that):
