Re: [amibroker] Measuring AFL Execution Times

Hello,
 
This method is good, however there is one bug in it.
The time retrieved by GetPerformanceCounter is in MICROseconds (not in milliseconds).
 
 
 
MICROsecond is 1/1000 part of millisecond and the timings retrieved using the formula provided
are actually 1000 smaller. So Param() call takes 1 MICROsecond (1 millionth part of the second).
 
So either you need to DIVIDE by 1000 to get milliseconds:
 
function Trace( Comment ) 
{ 
global LineNumber, TitleStr; 
PC = GetPerformanceCounter( True )/1000; 
Str = "# LN: "+NumToStr(LineNumber++,1.0,False)+", PC: "+NumToStr(PC,9.3)+" mSec., "+Comment; 
TitleStr = TitleStr + Str+"\n"; 
_TRACE(Str); 
} 
 
 
 
Or write MICRO seconds instead:
 
function Trace( Comment ) 
{ 
global LineNumber, TitleStr; 
PC = GetPerformanceCounter( True ); 
Str = "# LN: "+NumToStr(LineNumber++,1.0,False)+", PC: "+NumToStr(PC,9.3)+" uSec. (microsecond), "+Comment; 
TitleStr = TitleStr + Str+"\n"; 
_TRACE(Str); 
}
