Subject: 2.5.2-pre9 - HD performance degradation
Date: Mon, 07 Jan 2002 22:07:16 +0100 [thread overview]
Message-ID: <3C3A0E04.9020909@arpacoop.it> (raw)
I ran hdparm -t on my disks and discovered an abysmal drop in hard disk
performance since 2.5.2-pre1. Yesterday I ran fsck on all disks and it
took more than three times as much to complete under 2.5.2-pre9 than
usual. I am running SuSE 6.3, MB is Asus A7v, controller ATA 33 +
Promise PDC 20265.
These are the results for a disk, (ATA 100 IBM 307030),for the other
disks they are pretty the same.
Resuslts for "hdpam -t /dev/hdg"
Kernel 2.5.2-pre1 - 35 MB/sec
Kernel 2.5.2-pre4 - 15 MB/sec
Kernel 2.5.2-pre9 - 10 MB/sec
For the rest, it seems pretty stable, but I still get kernel panic on
cold boots from the AHA 2904 (AIC7850).
Cheers,
Carlo Scarfoglio
