On notebook running FreeBSD 7.0 on Pentium M 1.70GHz using configuration:

    server {
        listen      8000;
        return      404;
        access_log  off;

I have got these results via localhost:

ab -n 30000 -c 10       ~8200 r/s
ab -n 30000 -c 10 -k   ~20000 r/s

This means that this microbenchmark tests mostly TCP connection
establishment via localhost: keepalive is 2.4 faster.
