It doesn't show it, because you're using the default value for it. Anyway if you think login processes is the bottleneck, you can try if setting login_process_per_connection=no helps. http://wiki.dovecot.org/LoginProcess
Problem what I don
t know were is a bottle neck and I dont know how to find it. I turn on mail_debug and all other but it not show anything what I look.I just increes all things what may be was a bottle neck and... seams to fix it. But I really want to know what it is was.
Setting "login_process_per_connection = no" is much more scalable for large environments. Obviously there is a slight security trade off. You can confirm if it's a login bottleneck by looking to see if you have the maximum number of "imap-login" processes (default is 128) rather than just arbitrarily increasing everything.
