The test script is I used is here (requires svn trunk):

   http://people.apache.org/~joes/testing_apreq2_vs_http_body.pl

when I run it with an arg of 10000, here's what it produced:

Benchmark: timing 10000 iterations of apreq_args, apreq_body, http_body...
apreq_args:  2 wallclock secs ( 1.89 usr +  0.00 sys =  1.89 CPU) @ 5291.01/s (n=10000)
apreq_body:  4 wallclock secs ( 3.81 usr +  0.00 sys =  3.81 CPU) @ 2624.67/s (n=10000)
 http_body: 70 wallclock secs (69.84 usr +  0.00 sys = 69.84 CPU) @ 143.18/s (n=10000)

I'm guessing you benchmarked by throwing lots of requests at a
webserver, in which case you probably hit a bottleneck somewhere
unrelated to the actual parsing.
