I think that WMWare knows anything about cache miss
nor it cares about it. However, the performance of
modern systems depends greatly on the performance of
the cache. If there are a lot of cache misses, then no
matter what speed your processor runs, memory access
time burns all your processor cycles.
Besides, there are a lot of issues. For example, the
network performance. Page replacement algorithms, etc.
They too, greatly affects the performance. Rather than
spending time optimizing the whole kernel, why do we
spend most of our effort on the slowest part of it?
