@alec If you want to avoid connections at all cost, did you try running an IMAP proxy to see if you can gain some there?
Just found the link: http://www.imapproxy.org/
We use imapproxy in production for both HORDE/IMP and RoundCube. We have a proxy processes on each of our webmail servers which have permission to connect to IMAP as any user. Once the webmail client connects to the proxy, the proxy will hold a connection open to the imap server.
Have you made any performance measurements? How many users do you have? How many users are simultaneously online? How many connections are between imapproxy and IMAP server at the same time on average and at maximum? -- Dennis
We haven't done any measurements on roundcube without imapproxy, and I don't have the numbers for concurrent proxy<->imap connections (I'm looking into that).
I don't have stats over time, but right now I'd roughly estimate 4,700 proxyd processes across 15 web servers. _______________________________________________ List info: http://lists.roundcube.net/dev/
