    Is this from a internal network or external ? does any of your traffic pass through a proxy or firewall ? could you let us know much about your setup please especially around network and the server itself.
    Code:
    df
    top
    vmstat
    cat /proc/meminfo

    I have the slow delete issue as welll, it doesn't appear to be a hardware issue either. My resources are underutilized and the drives aren't overly busy when this occurs. Deletion of 1 message through the web interface can take 10 seconds. Everything else seems to work properly, good pop/imap/smtp speed.

    Your server is under very heavy processor load "load average:5.17, 4.55 4.03". What processes are using your system that you have an average of 4 processes running at once?

    Also it looks like besides running quite a few processes, about half of the processor is spent waiting on IO operations "46,9% wa". (This is mainly disk access)
