BTW, using embedded perl:

    server {
        listen 8010;
        access_log  off;

        location = /test {
            perl 'sub {
               my $r = shift;
               $r->send_http_header("text/html");
               $r->print("<h1>Hello ", $r->variable("arg_name"), "</h1>");
               return OK;
            }';
        }
    }

"ab -n 30000 -c 10 -k" has got ~7800 r/s.
