According to dmesg it's: | CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 5600+ (2900.03-MHz K8-class CPU) | FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs | cpu0 (BSP): APIC ID: 0 | cpu1 (AP): APIC ID: 1 I'm not sure if that qualifies as "really old". > I've put the benchmark dl: > http://blog.multiplay.co.uk/dropzone/bench_clock_realtime.c My output is: mcp:~>./bench_clock_realtime 1000000 | sort -rnk1 clock realtime micro-benchmark. 1000000 syscall iterations.

Do you think updating to -CURRENT might be worth a try?
