I'm testing oVirt 3.3 with GlusterFS libgfapi back-end. I'm using a node for engine and one for VDSM. From the VMs I'm mounting a second GlusterFS volume on a third storage server.
I'm experiencing very bad transfer rates (38MB/s) writing from a client to a VM on the mounted GlusterFS. On the other hand, from the VM itself I can move a big file from the root vda (libgfapi) to the mounted GlusterFS at 70MB/s.
I can't really figure out where the bottleneck could be. I'm using only the default ovirtmgmt network.
Thank you for your help, any hint will be appreciated.
