The test unjars some jars with ant twice; the second run of unjar is much slower on xfs then on ext3.
How do I get xfs to be as fast as ext3?
by hacking/fixing jar ? a quick test with your example data shows: extracting jar files using "jar" is **VERY** slow on xfs when overwriting existing files (extracting into empty directry only is *slow*... ;) "unzip -o arch.jar" extracts/overwrites *much* faster on xfs than "jar xvf" strace shows: jar overwrites files like this open("file", , O_WRONLY|O_CREAT|O_TRUNC, 0666) while unzip first deletes the the existing file: unlink("file") open ("file", O_WRONLY|O_CREAT, 0644) which is a lot faster on xfs (no difference on ext4 which is again much faster than any of these xfs tests;) so maybe you want to fix (un)jar to 1st delete existing files.... -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
