Respected Sir

I write simple C code( some calculations in for loop) and Time Stamped it.i
run that on my PC with 2.4 GHz,512 MB.but unexpectedly it took more time to
execute on XP Embedded than XP Pro.For 10,0000 iterations it took 49 seconds
on XP Pro and 1531 Seconds on XP Embedded. But when i comment out output line
cout<<i<<"\t"<<i*i<<"\t"<<i*i*i<<endl; in code

and made simple calculations inside loop , both XP and XP embedded took same
time.
Sir I want XP for some real time purposes.Plz Guide me ASAP.

Regards
 
Zalmay,

You're writing to a console window (using "cout") -- if you don't have
the correct accelerated video driver in your XPe build, you will notice
a dramatic slowdown from your XP Pro configuration. Also, things like
the video resolution setting and whether the console is in full-screen
mode -- using Alt-Enter -- will impact the performance.

What exactly are you trying to benchmark? If you're testing raw CPU
performance in XPe vs Pro, I would use a reliable 3rd party benchmark
(such as SiSoft Sandra). It will also test subsystem performance, such
as disk access, memory access, etc.

I shall ignore the 'sir' for now, aside from saying that the combination
of 'sir' and 'plz' breaks my brain.
XPe isn't ideally suited to Real-time applications. It can be used, but
there are better alternatives.
