[Red5] Performance question

[Debian User]

Thanks for your answer.

I have a problem with what you said:

When a user is pressing an arrow on his keyboard, i send this 
information to red5 server.
In this case, i don t know how to compute coordonates on red5 server. 
Should i put a thread that will computes coordonnates every seconds on 
red5 server ?

Thanks
