Subject: Terrible VM in 2.4.11+?
Date: Tue, 9 Jul 2002 00:11:37 +0200	[thread overview]
Message-ID: <20020709001137.A1745@mail.muni.cz> (raw)


Hello,

as of the last stable version 2.4.18 VM management does not work for me
properly. I have Athlon system with 512MB ram, 2.4.18 kernel without any
additional patches.

I run following sequence of commands:

dd if=/dev/zero of=/tmp bs=1M count=512 &
find / -print &
 { wait a few seconds }
sync

at this point find stops completely or at least almost stops.

The same if I copy from /dev/hdf to /dev/hda. XOSVIEW shows only reading or only
writing (as bdflushd is flushing buffers). It never shows parallel reading and
writing. /proc/sys/* has default settings. I do not know the reason why i/o
system stops when bdflushd is flushing buffers nor reading can be done.
