I've got DMA enabled, Multiple I/O, EIDE 32-bit and lookahead enabled in my /etc/sysconfig/harddisks file. Running that hdparm line gives me: /dev/hdb: Timing buffer-cache reads: 1204 MB in 2.00 seconds = 601.49 MB/sec Timing buffered disk reads: 96 MB in 3.00 seconds = 31.97 MB/sec ...clearly *not* fast. This is a Maxtor Diamond ATA 120Gb drive, 7200rpm, on an ASUS A7V8X-X mb. I'm running FC1 with a 2.6.3 kernel from kernel.org. Any suggestions for speeding up my I/O (or more info to provide)? TIA, -Don
