Hi Andreas,

The workloads are the same. I am using the Parsec stuff, by the way.

The number of instructions (sim_ticks) are also the same.

I'm using the default CPU (I guess it is atomic), no O3.

I did not change the latency for the different cache sizes. But the
question is if the cache miss rate should affect the time (more misses -
small caches - means more time, right?). If I increase the latency of
bigger caches, the behavior probably will be "more time spent with bigger
caches", the opposite.

Sorry if the text is confuse.

Than you!
