Someone have a performance question or a good tip to add to the list? The one thing that first pops to my head is some hdparm results I've had and if maybe it's either my kernel setup or how I'm testing with hdparm... Anyhow.. Raptors on SATA (Model Number: WDC WD360GD-00FNA0) (-c3 -u1 -A1 -W1 -d1 -a256 -M254 -m16 -X70 ) Kernel config CONFIG_SCSI_SATA_SIL=y There's an alternative driver, but haven't tested it... hdparm -tT /dev/hde /dev/hde: Timing cached reads: 956 MB in 2.00 seconds = 477.02 MB/sec Timing buffered disk reads: 116 MB in 3.03 seconds = 38.26 MB/sec hdparm -tT --direct /dev/hde /dev/hde: Timing O_DIRECT cached reads: 244 MB in 2.01 seconds = 121.26 MB/sec Timing O_DIRECT disk reads: 124 MB in 3.01 seconds = 41.17 MB/sec Laptop 7k60 (Model Number: HTS726060M9AT00) hdparm -tT /dev/hdc /dev/hdc: Timing cached reads: 1980 MB in 2.00 seconds = 989.94 MB/sec Timing buffered disk reads: 118 MB in 3.04 seconds = 38.81 MB/sec hdparm -tT --direct /dev/hdc /dev/hdc: Timing O_DIRECT cached reads: 364 MB in 2.02 seconds = 180.54 MB/sec Timing O_DIRECT disk reads: 120 MB in 3.04 seconds = 39.42 MB/sec I also can't set the raptors into UDMA6 tried -X70 with no luck.. Any suggestions? Thanks C. -- gentoo-performance@gentoo.org mailing list
