[Gluster-users] Gluster for RRD Data.

[Peter Mistich]

Hi,

I am new to gluster and have looked all over on how to tune gluster for 
rrd files and have come up empty.

I have a default install of gluster and am using the fuse client.

The issue is the performance of rrd updates are very slow.

here are the test I ran one on the physical box and one from the clients.

a little information about the setup.

I am running rhel 6.3 on the gluster server and 6.4 on the clients with 
a 10 gig network between the boxes.

any help would be great. I know there has to be something I can tune to 
get closer to speeds to the physical box.

Thanks,
Pete
