This would probably be true for single-tasking OS's, or non-preemptive multitasking OS's, like Network Appliance's servers or NetWare servers. For preemptive OS's, the cache is much less important, since the locality is much less coherent. So for benchmarks on FreeBSD, I think Tony is probably on the money.
