Ahh. I was working with someone else trying to figure out if the cache would affect the calculated bogomips. Looks like it would.
The machine I'm reporting shows 512K of cache though. I included a second machine as a comparison, and apparently choose poorly. That was the machine reporting no cache.
Would a machine with L1 cache disabled, but with 512K of L2 cache report around 4 Bogomips, or would the performance hit not be that strong?
