Have you enabled mod_spdy on your website?

Enabling it significantly improves performance in so many ways! Such as saving connections on your server due to multiplexing multiple connections, requesting all page resources in one shot.

Instructions on how to enable mod_spdy could be found here:
https://developers.google.com/speed/spdy/mod_spdy/

If you are playing with WebSockets a lot, there is this experimental chrome switch which enables WebSockets over spdy! --enable-websocket-over-spdy

Thanks +Mike Belshe :)
