[Gluster-users] GlusterFS performance with small files.

[David Whiteman]

Hi,

Thanks for the reply. Changing to mbox is not really an option, we are 
stuck with MailDir format.

All current cluster filesystems I've read into seem to have problems 
with small files.

I guess the only alternative seems to be a DRBD setup, but this would 
limit me to 2 nodes only and was the reason I was looking into GlusterFS.

Anyone know of any alternatives to GlusterFS that offer similar 
performance (with very small files) to NFS?

Thanks
