I run a cluster of Roundcube servers (3 ESX VM's on 3 ESX hosts, each
roundcube VM is allocated 2GB of RAM with 5Ghz over 4 VCPU's) with a
shared mySQL database (pair of Dell PowerEdge M610's with 16GB RAM) that
has active/active replication on.
Currently, this setup is serving about 45,000 users (not all at once, at
any one time there is about 120 HTTPS sessions per box) and it seems
reasonably quick. We did have issues where the roundcube VM's were
allocated 1GB of RAM, but adding the extra 1GB of RAM made a huge
The mail servers that Roundcube connect to are all either Dovecot or
I would suggest based off your specs maybe some additional RAM would
help (that reduced our load average per box from about 8-9 down to 0.5-1.
