[Gluster-users] glusterfs poor performance for my local machine (host and client on the same machine)

[Cool]

I'm not expert, but I can guess that to make the whole thing scalable, 
gluster needs to go through gluster client, then network, then gluster 
server, then native disk write, while native write does native disk only.

Again, it doesn't make sense to do such a comparison, or if single node 
fit you, get rid of gluster.
