Here is a video dated May, 2011:

(I finally managed to get a Youtube account since almost nobody can 
read a raw MP4)

I was using UDP to stream commands in&out : No noticiable lag in both 
directions. You may recognize an old version of MaxMSP, which make 
easy to link any MIDI hardware (aka "control surface").

HTTP is lightweight and can lead to comparable performance. It 
unlocks the HTML/AJAX technology at the remote end.

So no, the LSL HTTP server is not slow. It also allows inter-grid 
communication. It's probably the most underused feature of scripting.
