I use glusterfs3.3.0 as KVM storage, but I have found the performance in vm is poor.
I have the same problem as the below bug: https://bugzilla.redhat.com/show_bug.cgi?id=842254
the I/O performance is < 1% of my hardwares capability. Hopefully work on buffering and other tuning will fix this ? Or maybe the work mentioned getting qemu talking directly to gluster will fix this?
Best Regards.
