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. -C.B.
