How to profile your program using Intel's VTune profiler

Quick VTune Tutorial

VTune kicks butt. It's a sampling profiler made by Intel, so it can't give you a call trace, but it's so low-impact that you can profile anything, and it'll tell you where you're spending all of your time on a microscopic level.

memcpy() comparison with SSE

This program measures bandwidth of memcpy() versus bandwidth of a simple SIMD-using assember implementation, just to show that memcpy() really is quite sucky (at least the version included in MSDEV 6.0sp5)

Memory bandwidth optimization

Note that what I'm saying is sort of x86-centric, with specific illustration for Pentium II/III, although it'll also work on AMD and even on other platforms (like PowerPC). The more PC/workstation like the platform, the more truth this holds. DSPs with SRAMs aren't anything like this, though -- programmer beware.
