The Ops team may have spun up an ELB just for websockets, so they can use a standard port in TCP mode.

The gorouter itself supports websocket connections. The "cf logs" streaming logs is one user of websockets.
How you access it might depend on which CF you target. 
Look in ~/.cf/config.json for how "cf logs" accesses loggregator:
cat ~/.cf/config.json | grep Logg  "LoggregatorEndPoint": "wss://",
I'm actually surprised by the above - I thought PWS used port :4443 for websockets/loggregator.

Do you have any guidance/recommendations for running Web Sockets apps on Cloud Foundry ?
I am afraid that if application need to open multiple connections it may affect the performance of  the overall system. 
Any recommendation and pointer will help....
