Do you use POP3?
Yes. I don't have the stats right now but I'd say, on 2500 users,
60% are using IMAP, 40% POP3.But I had the feeling that it was the IMAP processes which were
causing the load, particulary because some IMAP users were complaining about low
speed while moving messages from mailboxes (I'm talking 1.0.14 here).
However, I don't know if it was a cause or a consequence...
Well, one change is that by default copying messages is now done using
hard links, but you could have done that with v1.0 also by changing a
setting.
So no big architectural changes ? Or maybe changes in the locking code ?
Not really.
What about the upcomming 2.0 ? Is the new master expected to provide
load improvement ?
No. It's mostly about making the master more modular.
