I would say it's probably bottlenecking on disk I/O based on what you're telling me. The quad core could have a shitty SATA chipset in it, causing poor I/O scores. If the times stop at 30 mins, it's probably the SATA controller that's reached its limit. Setting the controller to AHCI would give OpenBSD access to NCQ where available, but the driver would also have to be written to take advantage of this I would imagine. There would also have to *be* a driver for the controller, which wouldn't be needed if it's being run in legacy mode (IDE emulation essentially). If your hard drive comes up as wd0, it's set in Legacy mode. If it's sd0, it's in SATA/RAID/AHCI mode (dependant on manufacturer). -- Aaron Mason - Programmer, open source addict I've taken my software vows - for beta or for worse
