wbmw,

Simple. The trace cache is 12k uops. Applications contain structures called 'loops', which is code that runs over and over again.

I know a bit about loops, since I am a programmer, and it always made sense to make code inside th loops small, but most programs are written in high level languages. You don't really know what machine code will be generated, and in 2001, you shouldn't care.

Besides, Intel may increase the size of the trace cache in the future, or improve the decoders, meaning that the time one would spend worrying about optimizing for Willamette may be completely wasted.
