Good graphical HTTP trace program for OSX?

Solution 1:

You could use wireshark which has a graphical interface (and a CLI one called tshark). It has a menu entry called "Follow TCP stream". That way, you see all requests and answers from a given TCP connection.

Solution 2:

You can get load time, latency, speed, etc from Safari's Web Inspector. The Web Inspector's resources tab is a good place to start.

To enable the Web Inspector, the Developer menu needs to be turned on (Preferences > Advanced > Show Developer menu...).
