Slowness sending video for two RTP clients

Question

Hi
I'm testing a simple application where a server capture video from a web cam, apply an effect to it (the rotatio effect) and transmit the stream over RTP to any client that connects to it.
The clients that I'm using is an example applet that's called RTPAppletPlayer (or something like it).
The server first create and initialize the Processor. Then it create a cloneable data source and stores it.
The first client that requests a stream, I create a RTP session manager using the cloneable DataSource.
For the other clients thats request a stream, I do the same process, but instead of using the original cloneable DataSource, I create a clone DataSource and use it.
That's the architecture of my app. I hope that I was clear enough!
The problem is: The first client to connect can see a perfect image of my webcam. But second client gets a very, very slow stream. It only shows a few frames per MINUTE, while the first client gets a lot of frames per SECOND!
And it's not processor botleneck nor a network bottlneck. I only tested it in my home LAN. One of the the clients is the localhost for the server. The processor never gets too busy. I tried to raise the JVM priority, try a few changes in the code, nothign works.
No matter which client I use as the first one to open a session with the server, this aways will be the one to get the fast stream.
Anybody has experienced something like this before? Am I doing something wrong to create the clones or the RTP sessions?
Any help will be appreciated!
If you think it will help, I can post some of the code here.

I discovered what I was doing wrong.
I shuldn't create a SessionManager for each request, but use the same instead. Fro each new client that request the stream, I just call addTarget in the SessionManager. It works!
