You do know that gluster is not about single-node performance? You'll get far better performance by using RAID 0/1/5/10 on your local machine. Gluster gives you multiple machine redundancy (like RAID, but spread across multiple machines), and size scalability beyond what you can fit in one box.

From a single node that looks reasonable for gluster. You'd probably get 3-4 times that with native local access.
