Red Hat Bugzilla – Bug 712063
btrfs is dead slow due to fragmentation
Last modified: 2012-02-02 13:46:49 EST
Just to track the upstream bug.
Unless anybody thinks a speed of 500kb/s is acceptable, this *must* be fixed before btrfs is the default fs.
Mount -o auto-defrag with an upstream kernel.

Mention that in the upstream bug report. Once it has been validated to fix the issue, the upstream bug can be closed _then_ this bug can be closed.
In the meantime, as far as we know, the issue remains there.
And BTW, does this means that auto-defrag would be enabled by default in Fedora?
Yes the idea is that it will be turned on by default for fedora.

Do you have a patch for rawhide so we can try it there?
I guess autodefrag does the trick.
