If you're willing to do some more data collection, the next step that I recommend is to collect a system call trace for oth 1.3 and 2.0 (with the prefork MPM for the latter): strace -o [output file] -p [pid of one httpd child process] and run "ab -n1 -c1 [your test URL]" and post the output for 1.3 and 2.0.
