Hi, I just installed FreeBSD 6.2-BETA3 (amd64) on a Dual Xeon DC 5140 w/ 4GB of RAM and a 3ware 9550SX connected to 8x Seagate 250GB SATA drives (RAID5) and instead of the normal great performance I get from FreeBSD, it's taking over an hour to do a 'portsnap extract' and while it's doing it, the system gets very unresponsive (trouble logging in via SSH, commands sit for several seconds before executing). On two other machines with the same 3Ware 9550SX (and disks) but dual Opteron 248s, the portsnap extract operation only takes a short (relatively) amount of time to complete. The RAID array is fine, it's not rebuilding or degraded of anything. I've tried turning the write cache on the controller on/off. Where do I start looking to find the culprit? gstat reports the following during the portsnap extract: L(q) ops/s r/s kBps ms/r w/s kBps ms/w %busy Name 416 70 0 0 0.0 70 160 12149.0 101.7| da0 Cheers Phil dmesg: Copyright (c) 1992-2006 The FreeBSD Project.
