[Gluster-users] Tune and optimize dispersed cluster

[Marcus Pedersén]

Hi all,
I have setup a dispersed cluster (2+1), version 3.12.
The way our users run I guessed that we would get the penalties
with dispersed cluster and I was right....
A calculation that usually takes about 48 hours (on a replicaited cluster),
now took about 60 hours.
There is alot of "small" reads/writes going on in these programs.

Is there a way to tune, optimize a dispersed cluster to make it
run better with small read/writes?

Many thansk in advance!

Best regards
Marcus Pedersén

You should not run disperse volumes with small IO.
2+1 disperse is gaining only %25 over replica 3 with arbiter...
