Having the accept filters turned on in the kernel is a huge win for
Apache.  See the tuning(7) man page for other details of interest.  As
for which MPM, last I heard UNIX folk were better off using the
pre-fork MPM and not the threaded MPM.  This may have changed, but I'd
bet dime to dollar you'll get better stability out of the pre-fork but
a smaller memory footprint out of the threaded MPM.  -sc
