Red Hat Bugzilla – Bug 31161
aic7xxx driver is extremely slow
Last modified: 2007-04-18 12:32:05 EDT
Compaq Deskpro 6000 system. AIC-7860 Ultra SCSI host adapter on board.
Ultra Narrow Controller
driver version 5.2.3/5.2.0
Steps to Reproduce:
1. boot the system
2. hdparm -t /dev/sda
Actual Results: about 1.5 meg/sec
Expected Results: about 8.5 meg/sec Red Hat 7.0 on the same box/drives.
Does this still show with the latest kernel available by up2date / rawhide ?
Several aic7xxx performance bugs are fixed since the original wolverine-kernel.
tested with 2.4.2-0.1.25. got speed over 8 meg/sec which is normal.
sounds fixed to me, closing
