I assume that means 2 CPUs with two cores each, aka socket 771

This is easy to check: either rebuild a kernel without "options SMP" or
disable processes by setting machdep.hlt_cpus (see smp(4)) or set
hint.lapic.X.disable=1, then run the

The difference was there both when using memcpy, and whe

Now, in simple memory access operations, I see the freebsd system being
noticably slower than the linux system. A simple C program that co
