Hello,
Inside parallelhashlist.zip i have put a new timer.pas that compiles
correctly
under both Win32 and Win64, i have changed the Tick method inside
timer.pas and added the 64 bits parts so that it works correctly under
Win64:
Here is the new Tick method:
----
function TLkBaseTimer.Tick: int64; register;
//asm
// rdtsc;
//db 0fh, 31h
//end;
asm
rdtsc
{$IFDEF CPU64}
shl rdx, 32
or rax, rdx
{$ENDIF CPU64}
end; { GetCPUTimeStamp }

How to use the timer to time in microseconds ?
Like this:
Call Timestart() first like this:
HPT.Timestart;
and after that you can write the Time in microseconds like this
writeln('Time in microseconds: ',hpt.TimePeriod);
Please look inside test1.pas inside parallelhashlist.zip i have given you
an example on how to use timer.pas to time the throuput of your
multithreaded
program...
You can download parallelhashlist from:
