Part of it is caused by a first sync to a new storage with a new filesystem which should improve our speed on the backend a lot.
Just out of curiosity: Which filesystem did you trade in for what? Did you do specific benchmarks before?
As we use SLE11 SP2 there are only two valid choices: XFS and btrfs and in our benchmarks (massive parallel read and write of small files with sync in between) btrfs won hands down. But we'll do some more tests before we switch (and you will notice if we switch because we will need to be down for several hours to do the final sync). One issue I'm already facing while syncing: btrfs has a pretty strict limit on hard links between files in one directory - and a :full tree can have quite some hard links. But that seems to be fixable. Greetings, Stephan -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org
