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

<div>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.</div>

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

<div>but the truth is it's much worse than use my native
harddisk, that's is why I post my question, any setting is
wrong with me ?<br>
