[imp] IMP very slow on Centos 5

[Wayne Catterton]

Thanks,

Ok, I've got horde setup to use imp for auth, and imp is set to auth
through imap.  I'll leave this alone.

I've checked the logs, and don't see any errors or problems.  I even set
dovecot to log to a seperate file (I normally have it set to syslog), and
errors to another, I watched both files and didn't see any problems.

One thing I did notice on the logs though, is after I click (say to check
my mail in imp), it's a good 1-3 seconds before I see activity in the log,
but there isn't any error messages or anything like that, all appears
normal.

In squirrelmail when I click to check mail, it's instantly up and the log
is instantly updated, no laggyness or anything like that.

I thought (but I'm not an expert), that if squirrelmail works and is fast,
than IMP should be as well, since they are both using the same auth
method?

Is there anything within the config's of IMP to where it might be trying
some other methods before getting to one that works?  or something it
might be doing before the auth, that's slowing it down?

Is there anything additional I need to setup in dovecot?  Again, I'm not
an expert, but squirrelmail does just fine with it.
