We have noticed that the IMAP servers appear to be under much less
load and utilising drastically less RAM than the POP3 servers and I'm
wondering if there is a reason for this as we have seen some swapping
onto disk yet we are only handling 500 concurrent POP3 connections to
each server at any given time compared with over 600 IMAP connections.Am I to take it that this is expected behaviour?
If anyone can shed more light on this I'd be very grateful.
More specific information would be helpful. Load as shown through top doesn't really tell anything. Are you simply seeing memory pressure? Is all that RAM being used for block device cache or actually eaten by the pop servers?
