Hi Leo,
Gluster is quite smart, but in order to provide any hints , can you provide
output of 'gluster volume info <glustervol>'.
If you have 2 more systems , keep in mind that it is best to mirror the storage
on the second replica (2 disks on 1 machine -> 2 disks on the new machine),
while for the arbiter this is not neccessary.
What is your network and NICs ? Based on my experience , I can recommend at
least 10 gbit/s interfase(s).
Best Regards,
