<br>
I am new to gluster and have looked all over on how to tune gluster for rrd files and have come up empty.<br>
<br>
I have a default install of gluster and am using the fuse client.<br>
<br>
The issue is the performance of rrd updates are very slow.<br>
<br>
here are the test I ran one on the physical box and one from the clients.<br>

<br>
<br>
a little information about the setup.<br>
<br>
I am running rhel 6.3 on the gluster server and 6.4 on the clients with a 10 gig network between the boxes.<br>
<br>
any help would be great. I know there has to be something I can tune to get closer to speeds to the physical box.<br>
<br>
Thanks,<br>
Pete<br>
