<p>Hi everyone!</p>
<p>I've asked this question before, but I don't think my subject
line got the right people's attention, so apologies for
re-posting.</p>
<p>We've got a mail server with about 10,000 e-mail accounts, all
sharing their Maildir mailboxes on our 3-node Gluster array
configured as a replicated volume. The performance of this Gluster
share is quite poor, and it takes a long time to fetch peoples'
mail, especially when they're using webmail.</p>
<p>Every node in the Gluster array has their RAID array configured
as RAID5, so I'd like to improve the performance on each node by
changing that to RAID0 instead. I think that that Gluster's data
replication is good enough to keep our data from being lost in the
event of a disk failure, but I want other people's opinions on the
matter before we go doing something so drastic. At the very least,
I need someone's opinion on this particular subject before we do
anything.<br>
<br>
One other person has recommended some Gluster settings to improve
Gluster performance for small files, but considering the IO and
CPU overhead of Gluster, I'd have to wonder about its usefulness.
