Sorry, I can't understand what is real problem here? Gluster is not 
fast, but I don't think problem is in client in userspace.

I guess it is possible to write kernel module  :-)

Never had problem in this on 10Gbit network, we can't saturate 10Gbit  
(well, really 20 ) using gluster.

btw, gluster 4 was promised to have different networks for clients and 
inter-server replication ( healing) ,

but when glusterd2 arrived it has nothing about this.

Anyway, we are quite happy with our current gluster setup, which allows 
us have just 3 servers and no shared storage in several places,

not suitable for all our workloads though, so gluster is not universal tool.
