Hi all
I'm using on my cluster glusterfs with unify with numa scheduler.
When I write into gluster partition on one node, of course it's fast (write on
local disk)
after that when I read from another node the perf is good ~ 95Mo/s (on 1Gbits/s
switch)
But if I write into this file from another node the perf is very bad ~
8Mo/s. I known that's not the normal situation, but this can append when
the file is create on one node, and append in other node sometime later.
This performance ~8Mo/s on 1Gits/s network is normal ? How can I improve
this ?
All node of my cluster is identical and have 16Go Ram, two disk at 15000rpm.
Regards.
