Sudden performance drop

Ah! That's probably it...

I have *lots* of sockets in TIME_WAIT state, which makes sense - I open a
connection to the upstream server, make a request, read the response and
then close the connection.

I suppose I have two options:

1) mess with /proc/sys/net/ipv4/tcp_tw_reuse and friends
2) use connection pipelining / persistent http connections. Need to check
the Netty docs for this I guess.

thanks,

Phil.
