I ran FUSE mounts for a couple of months then switched to NFS. In 
general I saw an approx 2x improvement in read performance, and writes 
appeared to be a little quicker. Since my environment is 'mostly reads', 
as NFS utilizes the OS filesystem cache I saw a substantial drop in 
network traffic between Gluster nodes.

I was also never able to get FUSE to mount volumes with an explicit 
SELinux context set. Not sure if it's a bug in FUSE on RHEL6, or just 
something broken with FUSE, but it just ignored the secontext= mount 
parameter. NFS works with this, so I was able to run SELinux in 
enforcing mode while using Gluster.
