Sleep is not a counter, it's a 'pause' in your code execution

Suspends the execution of the current thread until the time-out interval elapses.

Code:

invoke Sleep,1000 ;pause for 1000msec or 1sec

GetTickCount can be used as a 'counter'

Retrieves the number of milliseconds that have elapsed since the system was started, up to 49.7 days.

Code:

Call [GetTickCount] ;x
mov esi,eax
...
...
Call [GetTickCount] ;y
sub eax,esi ;eax has the time (in msec) that was needed to execute the code between x and y

i wish someone could explain me music theory so good.. Smile

There is QueryPerformanceCounter (and QueryPerformanceFrequency). The high-resolution performance counter gives more accurate and faster timing than the tick counter.
