I just finished running 6 sets of (make clean + buildworld + buildkernel), toggling machdep.cpu_idle_hlt between enabled and disabled each time (3 of each). Hardware: 2 x Athlon MP 2600+ on a Tyan Tiger 2466 mobo with 768MB memory Disks: 4 x 36GB 10k rpm in RAID-5 config on a SmartArray 6302/64 controller (ciss) Software: RELENG_6 from yesterday machdep.cpu_idle_hlt=3D1 45.01 46.12 45.30 machdep.cpu_idle_hlt=3D0 43.47 43.09 43.29 Looks like machdep.cpu_idle_hlt=3D0 shaves ~2 min off the build-time on = my server. /Daniel
