I recently switched/upgraded from Caldera OpenLinux 2.3 (kernel 2.2.10) to Suse Professional 7.2.
While there's much I like in the new setup, hard drive performance isn't on the list! ... Results for "hdparm -t" (rate for buffered disk reads of 64 MB):
Suse compiled 2.2.19 kernel ~ 9.5 MB/sec self-compiled 2.2.19 kernel ~11.5 MB/sec self-compiled 2.2.18 kernel ~11.5 MB/sec Caldera complied 2.2.10 kernel ~15.5 MB/sec
What hdparm settings do you use? The following is from an old and slow system (550 MHz PIII, Intel 440BX, FUJITSU MPF3204AT HD). # hdparm -v /dev/hda /dev/hda: multcount = 16 (on) I/O support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 2491/255/63, sectors = 40031712, start = 0 # hdparm -t /dev/hda /dev/hda: Timing buffered disk reads: 64 MB in 3.27 seconds = 19.57 MB/sec -- Alexandr.Malusek@imv.liu.se
