Indeed, that was the problem.
Once I've got compressed content, we go up to about 10 req/s, still
not close to the 17 req/s of Apache. I think I don't have evidence of
the speed of Nginx + mongrel_cluster for my particular application at
least, so I'll get back to Apache 2.2.3 + mod_proxy_balancer.
