No change here.. My default compiler settings is as follows:
<CONFIG>
<Compiler Value="C:\FPC\2.0.2\bin\i386-win32\ppc386.exe" Date="863670948"/>
<Params Value=" -S2ci -OG1 -gl -vewnhi -l -Fu.
-oC:\Temp\t3\fpcBench.exe fpcBench.lpr"/>
</CONFIG>
I have tried the new code as you mention, also tried different
performance compiler settings, and it make no difference here. The
elapsed time is always the same.
My system specs:
Dell Inspiron 9100 (laptop)
CPU: P4 3000Mhz
Mem: 512Mb

Thanks for trying that!
What switches did you use?
Can you try with this switch: "ppc386 -gl fpcBench"
And can you also try this one with no switches:
program fpcBench;
{$mode objfpc}{$H+}
{ $APPTYPE CONSOLE}
uses
SysUtils;
procedure fn;
var
x: double = 0;
i: double = 9999999;
startTime: TDateTime;
begin
startTime := Now;
while (i > 0) do i := i - 1;
Writeln('Elapsed: ' + IntToStr(DateTimeToTimeStamp(Now - startTime).Time));
end;
begin
fn;
write;
end.
Thanks a lot!
