Unfortunately we are not able to reproduce this slowdown. Would you

FWIW, I notice the same (I'm not the OP). My main workstation (Athlon)
runs 2.6.15-rc1-mm1. Vim needs 4 to 12 seconds to close any file, mutt
is very slow on sending email, backups take several hours and in general
anything done on the filesystem seems slow. This system has one IDE
disk.
Scrips are locked when vim closes and bash/perl complain when they try
to read/execute the script.
The strange thing is that another system running 2.6.15-rc1-mm2 does not
have this slowdown. There are no Reiser4 updates in -mm2 AFAICS. This
system is a Via Epia with Reiser4 on lvm2 on 4xSATA.
Is this 2.6.14-mm2 bad sync/fsync performance reproducible on fresh
created reiser4 too?
I'll try.
Are these values stable reproducible? If you run this test several
time -- do you have the same results?
Vim is always very slow on close (:wq) for me.
Would you please send df -T output
# df -T /
Filesystem Type 1K-blocks Used Available Use% Mounted on
/dev/hda2 reiser4 232423180 166976448 65446732 72% /
and 2.6.14-mm2 config file?
2.5.16-rc1-mm1 below.
Did you try this test on ext2? If no -- would you please try it on
ext2 for the same kernels and send us the results?
If I open and edit a file on /boot, which is ext2 on hda1, vim reacts as
expected. Quick and without a single delay.
# echo "foo" > /boot/test
# time vim +"s/foo/bar/" +"wq" /boot/test
real 0m0.016s
user 0m0.000s
sys 0m0.000s
# echo "foo" > /root/test
# time vim +"s/foo/bar/" +"wq" /root/test
real 0m9.667s
user 0m0.000s
sys 0m0.020s
/dev/hda2 on / type reiser4 (rw)
/dev/hda1 on /boot type ext2 (rw)
Anything I can do to help?
Yes, thank you.
Which iosched do you use?
Would you please repeat the vim/reiser4 test for each iosched and send
us the time values?
Something like
for i in cfq noop anticipatory deadline
do
echo $i > /sys/block/hda/queue/scheduler && cat
/sys/block/hda/queue/scheduler && echo "foo" >/root/test && time vim +"s/
foo/bar/" +"wq" /root/test
done
Thanks,
