Saw this on the qmail list and was intrigued. Good article, but
disappointing to find that in their tests the speed winners were
Linux, Solaris, Windows, and FreeBSD -- in that order.  Is this due to
FreeBSD's conservative disk commits/writes, or possibly thread
inefficiencies, or something else? I find it hard to conceive of
Windows implementations of anything being faster, but...

    SysAdmin has an article online by some of the top technical people
    at Lyris (remember Lyris?):

    Title: Which OS is Fastest for High-Performance Network Applications?
    http://www.sysadminmag.com/newsletters/feature/

    They use their MTA as a comparison tool, and crank it up to 
    the equvalent of a concurrencyremote of 3000, though they 
    don't seem to get much of a performance boost past 1000 on
    the hardware they're using.

    One of their conclusions is that their asynch multi-threaded
    software model outperforms the process based model which qmail
    uses.  Is their methodology convincing?  Well...

    However, and interesting read.
