dovecot - Dec 2010 - director in large(ish) environments

Hey all, just wondering who here is running the director service in a larger
environment. I just switched our whole production setup to the director and am
quite pleased with the result. We're doing a peak of about 25000 tot 30000
concurrent sessions on 3 servers. But ive shut 1 server down a couple of days
ago to see what would happen and 2 servers carried the load easily. (16 CPU,
24GB memory servers).   If others are using the director on larger setups maybe
we can all post when things do or dont work well.

Now to see if the solution is better than the problem :)

Cor

Can i ask how are you storing your mail ? like, NFS, gfs, ocfs2  etc

and with type, like  mbox, maildir, sdbox etc..

In my system we are not usign director, using IPVS  but having lots of IO
wait problems!

Thanks!
