[alex]

Hi

imaptest user=user host=host pass=pass msgs=50 clients=100

   26    5   11   25   20   30   10   14   18   20   42 100/100

from what I have seen the results look pretty low , but what I can't 
really find is the meaning of numbers under each imap command.
Can anyone explain what this numbers represent.

Thank you
Alex
