I think they should be able to. Which kernel version are you running? I am mainly using 2.6.15 and 2.6.16 at this time. > > /tmp is residing not on the sata hdd but on an old ide > > disk doing 7200 rpm. That is one way to slow down /tmp. Usually the oposite is desired,hence the often used tmpfs for /tmp. > can you please measure the speed you're getting on > VT8251 / SATA? Well the speed I get here is: Asus A8V Deluxe: Via VT6420 SATA controller with WD2500JD drive: Timing buffered disk reads: 172 MB in 3.01 seconds = 57.17 MB/sec Asus P4P800: Intel ICH5R SATA controller with WD1600JD drive: Timing buffered disk reads: 172 MB in 3.01 seconds = 57.21 MB/sec Asus P4P800: Promise TX2200 SATA controller with WD2500JD drive: Timing buffered disk reads: 176 MB in 3.02 seconds = 58.21 MB/sec Asus A7N8X-E Deluxe: Sil3112A SATA controller with WD1200JD drive: Timing buffered disk reads: 152 MB in 3.04 seconds = 50.07 MB/sec If it gets a lot less than that I really wonder if something is keeping the disk busy, or if there is another problem with the setup of the system.
