Hello,
The reason for my mistake was that actual time spent in some calls is much lower
than reported by the method presented in UserKB.
This is so because the DebugVIew overhead. Often outputting text to debugview
takes
much more time than the function being measured.
For example if you measure the time needed to call Param() function 1000 times:
GetPerformanceCounter( 1 );
for( i = 0; i < 1000; i++ )
{
x = Param("test", 1, 0, 100, 1 );
}
Title=""+GetPerformanceCounter(1)+" milliseconds";
It will show up that it takes 5 milliseconds to call Param() 1000 times. So
single call is actually 5 microseconds,
not 1 millisecond (1000 microseconds) as reported by the method presented.

Hello,
Please ignore previous post.
I made mistake, the RESOLUTION is in microseconds, not the UNIT.
The UNIT is millisecond but resolution is upto 0.001 millisecond = 1
microsecond.
