Thank you, Perrin, for your perspective. Though it is a bit 
disheartening. :-}

I can't try the exact setup on another machine quickly. But, I looked at 
the output from top on two other machines that have the same httpd.conf 
and startup.pl, but different versions of the kernel, mp2, apreq2, and 
hardware.

I'm seeing similar behavior on all three, though it is worst on the two 
systems with the same kernel. The two with linux 2.6.10-1.12_FC2smp both 
have about 4M shared. One with linux 2.6.8-1.521smp has 14M shared, 
still not as much as I would expect.

The main difference between the 4M systems is that one is using mp 
1.99_21 and the other mp 1.99_17. The 14M is using mp 1.99_17.

What do y'all think would be my most fruitful next step, besides testing 
out a new machine? Should I switch to static mp2? Non-threaded perl? 
Eliminating perl modules to see if there is one causing the problem? Prayer?

Take care,
