I'm not saying FUSE is killing perfs :-) My point was more likely : be 
careful, if you mix up GlusterFS + Windows (caching system on C:) + 
FUSE, then you *could* have something like race condition which could 
affect perfs.

I haven't tested out MFS, happy if this is not reproducing, then :-)

Indeed. As said though, CephFS is also not perfect. If people want to 
choose Ceph, then it's better to boot from volume with Cinder-based RBD 
(RADOS Block Device) driver.
