Making rockbox r15613, under NetBSD 4.0_RC4 with an ACPI MP kernel, on a single processor Pentium 4 2.8 GHz system with Hyper-threading enabled in the BIOS:

gmake:		164.12s real   133.35s user    30.01s system
gmake -j 1:	163.59s real   132.76s user    29.97s system
gmake -j 2:	141.67s real   220.55s user    45.87s system
gmake -j 3:	140.58s real   223.93s user    44.82s system

Ignoring system time, this shows about a 17% improvement in runtime.
