Hi; After switching ext3 to xfs, i realize system starts to _really_ unresponsive and extracting tarballs, copying or deleting files or checking out svn repositories are really slow, so i basically try to measure some for both xfs and ext3 with same computer, same kernel (2.6.18.6), same disk, here are the results
* between all tests i dropped caches * i already tried to change block device's scheduler to as, noop and cfq, nothing really changes * i already tried 2.6.20-rc5 and 2.6.20-rc5.1.rt8.0085 which Ingo provides but again nothing really changes Kernel Tarball -------------- a) XFS [EMAIL PROTECTED] ~ $ time tar xvf linux-2.6.19.tar.bz2 ... real 2m16.865s user 0m21.113s sys 0m2.426s b) EXT3 [EMAIL PROTECTED] ~ $ time tar xvf linux-2.6.19.tar.bz2 ... real 0m34.192s user 0m20.624s sys 0m1.771s Deletion -------- a) XFS [EMAIL PROTECTED] ~ $ time rm -rf linux-2.6.19/ real 0m50.902s user 0m0.064s sys 0m1.378s b) EXT3 [EMAIL PROTECTED] ~ $ time rm -rf linux-2.6.19/ real 0m1.162s user 0m0.031s sys 0m0.411s Copying ------- a) XFS [EMAIL PROTECTED] test $ time cp -r ../linux-2.6.19 . ... real 1m42.833s user 0m0.124s sys 0m2.621s b) EXT3 [EMAIL PROTECTED] test $ time cp -r ../linux-2.6.19 . ... real 0m38.456s user 0m0.166s sys 0m2.744s I'm not sure these are normal numbers or its a regression (i'm just starting to use XFS) so any hints will be appreciated.
