Last time I tried reiserfs it also slowed down significantly during BackupPC nightly operations, so any claims of "it's way faster than ext3" should be backed up with BackupPC specific benchmarks, please. ext3 performance while not stellar is consistent. Tomasz, it would be interesting to see how many IOPS your array is getting during nightly operations and whether the behavior changes significantly before/after the perceived slowdown after dropping caches. After things slow down again, do they speed up again after dropping the caches? It would be interesting to note if the increased IO is actually from nightly processing things faster, or simply increased IO from having no more filesystem data in cache and things are actually progressing slower (though they appear faster because more IO is taking place). -Dave ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
