We want to use Roundcube 0.5.1 on Linux (RHEL 5.6 x64). We want to use RCU& mysql in the same host, and we will have a maximum of 1.500 concurrent users.
with 1500 concurrent users you mean 1500 different users connected to the web interface at the same instant? if so you will need more than a single web server and, perhaps, also a mysql cluster on different hosts than the web servers. (also don't forget to use imapproxy to avoid to start/stop imap connections every click of the user)
1500 imap concurrent connection on a dovecot server is big, but 1500 concurrent webmail users are a huge load for the servers
How much memory does roundcube uses? Any real-world experience?
it depends on your apache and php configuration... to have real numbers you should measure it on a staging box with your apache and php configuration and some users with mailbox and folder sized like the real mailboxes on the production environment.
