optimizing c++ code (on win32 platform), all the techniques you know?

Hi,


"What methods do you ever use to optimize the programs?"


We're developing a graphics chip emulator in C++, but it's very slow
for big scenes. Even though this is a cross-platform software, I only
want to optimize it on the Win32 (Windows 2000/XP) platform.


I've tried the following method to optimize it:


* Boost.Pool - a fast memory allocation algoritm, fixed-size chunks.
<http://www.boost.org/libs/pool/doc/index.html>


* Whole Program Optimization with Visual C++ .NET
<http://www.codeproject.com/tips/gloption.asp>
I almost turn on every possbile Visual C++ options to optimize the
speed.


* inline every possbile function




Not tried yet:


* Improving Runtime Performance with the Smooth Working Set Tool
<http://msdn.microsoft.com/msdnmag/issues/1000/bugslayer/default.aspx>
I don't think it will help much, because our program is about 500KB.
Or not?


* Recompile the CRT with _fastcall calling convetion


* Link single-thread CRT instead of multi-thread CRT
We don't use many CRT functions.


* Distributed Computing

Uh, not feasible. I am looking for "fast" approches, like a compiler
option, etc.
