Hi'all,
Anyone remember this thread:
"severe slowdown with 2.4 series w/heavy disk access"
http://hypermail.spyroid.com/linux-kernel/archived/2001/week52/0266.html
It describes the tendency of 2.4 series kernels to slowdown under I/O load. Well, that problem still seems to be alive and kicking. And no, it is not related to reiserfs as I previously suggested in this thread:
"Abysmal interactive performance on 2.4.linus", archived here:
http://www.uwsg.iu.edu/hypermail/linux/kernel/0111.1/0911.html
I removed the last reiserfs partition quite some time ago, currently running mostly ext3 with ext2 root fs.
The systems use IDE disks, I don't have any SCSI-systems handy to test whether this might be IDE-only (anyone?). Currently running 2.4.18 (with preempt and lowlatency, but the problems are NOT related to those patches as they also hit unpatched kernels) on SMP (Abit BP-6 yeah yeah I know but it does not seem to be specific to the BP-6).
Does anyone else see these problems? Specifically, does anyone with a SCSI-based system see this happening? Also, does anyone who uses only ext2 (no ext3 or reiserfs, let alone jfs/xfs or any other journaling fs) see this?
Cheers//Frank
