Of interest to you might be using a scratch disk space to store the 
indexes on a/the local mail server; I just did a bit of math for you 
(well ok, a 'bc' script did the math) and with 90.5gigs of email in 
Maildir folders via NFS, we have 372megs of indexes on the local disks 
for performance gains.

mail_location = maildir:~/Maildir:INDEX=/var/spool/dovecot/indexes/%1u/%u

I'm not sure the space your 100K+ mailboxes take, but maybe you can use 
the above numbers to do some math and see if you can do indexes like that.
