[Gluster-users] Dispersed cluster tune, optimize

[Marcus Pedersén]

Hi all,
I have setup a dispersed cluster (2+1), verision 3.12.
I guessed that we going to get punished by small read/writes...
and I was right.
A calculation that usually takes 48 hours
took about 60 hours and there are many small read/writes
to intermediate files that at the end get summed up.

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


Many thanks in advance!

Disperse volumes are not best suited for small read/writes.
Probably if you can tell us more about your use case, we can come up with some options which could help you.
- Are you using fuse mount or nfs mount?
- Are these small writes sequential or random?
