It's not to do with mail size, it's to do with number of messages in any one 
mailbox.  The file system underlying it will also effect this. 
One of my mailboxes currently has 10,000 emails in, and it's still not showing 
any signs of becoming any slower.

I imagine people's milage might vary with this kinda thing, but that post 
suggested all he changed was the mail server, not the file system, or 
anything else. (I presume he didn't - he installed them side by side)

Also, if you're interested, this is quite interesting

"The Cyrus IMAP Aggregator transparently distributes IMAP and POP mailboxes 
across multiple servers. Unlike other systems for load balancing IMAP 
mailboxes, the aggregator allows users to access mailboxes on any of the IMAP 
servers in the system. "
"The software described below is now available as part of the Cyrus IMAP 
distribution, versions 2.1.3 and higher. Please refer to the documentation 
with the source for setup and install instructions."
