Hello When discussing R4 ( http://forums.gentoo.org/viewtopic-p-6151767.html#6151767 )some users mentioned slow fsync and this way to reproduce: Get a directory full of directories and small files by extracting portage to test dir http://mirror.bih.net.ba/gentoo/snapshots/portage-20100127.tar.bz2 ls -R /mnt/media/test/ | wc -l 177073 Do a: time chown -R portage:portage /mnt/media/test/ Then : time sync real 40m9.350s user 0m0.000s sys 0m4.884s Throughput was around 80kb/s on a WD50000AAKS, no cryptocompress, mounted with noatime, kernel 2.6.30 Is this normal, and why people tell me that ext4 and btrfs do this in "several seconds" Does the modification hits the platter for them or is it still in buffers?
