[Dovecot] the most serius problems [part 1]

[Farkas Levente]

hi,
I try to collect out most serious problem with dovecot. so I write a 
series of mails:-)
the first on is the load.
has anybody else use dovecot in a real enviromnt with at least hundreds 
of users and at least 50 concurrent user at the same time?
it seems to me no one else just me.
the weekend I move the whole mail system to a quad P4 with 1Gb ram and 
this server do nothing just imap. yesterday evening I have to delete all 
.imap.index and other dovecot specific files. and as I wrote today 
morning the load was about 20-30 !!!. but even in an average day the 
load is over 2-3 white the cpu load is 1-2% in each of the 4 processor.
the system is totaly unusable. what more today I've got other errors. of 
course all the time when I can't find the colution I try to escape to 
the latest cvs. today finally I compile a new courier install it to 
another port and those clients which can't connect to dovecot 
reconfigure to courier. but they are not compatible!!! I have to set 
root directory to INBOX in courier while not for dovecot and this is a 
real big problem. is there any way to compile dovecot to use INBOX as a 
root directory? since in this case at least there is a chance to switch 
to courier without reconfigure 300 OE6.
I try to help to find out the reason for the load in any way, but it 
seems to me than it's better to change to courier or cyrus since our 
users getting angry not to mention my boss.
