Any problems with large number (160) of upstream servers (mongrels)?

Nginx does not reuse connections -- for every request, it connects to
the upstream Mongrel, sends the request, reads the response and then
disconnects. This probably does not scale very well to lots of
upstreams; a lot of time and system resources will be spent just on
TCP and socket bookeeping.

What was the load like when you experienced the problem?
