[Gluster-users] GlusterFS Preformance

[Mickey Mazarick]

Just a not, we have seen a pretty significant increase in speed from 
this latest 2.03 release. Doing a test read over afr we are seeing 
speeds between 200-320 mB a second. (over infiniband, ib-verbs)

This is with direct IO disabled too. Oddly putting performance 
translators on the clients made no difference. 

We cued up 10 servers to read a single file simultaneously and got about 
~30-50 mB a sec from each client, totaling up to ~400 mB a sec on a 
single file (read from 2 servers, by 10 servers).
We are really happy with these numbers for a virtual cluster so, most 
single drives won't read at those speeds.

Thanks!
