Also note that a lot of performance on ia32 can depend on cache
thrashing. You want to maintain memory locality otherwise you may get
confusing results. If you are using the wall clock for timing, keep an
eye on your disk light to as VM is not impossible without some care
but the cache may not be as appreciated.
This means parameter and data changes that cause flow or "small"
buffer size changes can make important differences in speed unrelated
to raw instruction or access count etc.
