Bug Description
Even on localhost, where sockets should short circuit, the daemon transport is extremely slow. A program I wrote using the local transport takes ~0.3s, whereas the daemon transport takes ~4.0s.

Pushy can be quite chatty, with many small packets sent. Disabling Nagle speeds up Pushy dramatically, by eliminating delays in sending these small packets. After setting TCP_NODELAY, the daemon transport operates at a similar speed to the local transport (at least on the localhost).
