how's websocket's response time calculated?

Posting here hoping someone will beat me on reading the source to dig out.

I'm doing a ping pong test to see if websocket can give us any performance boost in existing infrastructure comparing to http requests with keep alive on.

So, in the websocket report, how's the response time calculated. I'm a little confused. Does it mean:

1. the time client send a message and getting an ack from server saying they've gotten the message
2. or the time includes when the pong message has been received in the client.
