jit.net.send - matrix 640 x 480 sent over another computer

    I trying to separate my video capture on another computer so I can increase my FPS for process on the second computer.
    I'm using jit.net.send to send a 1280 x 480 matrix (luma mode) Sice I have 2 cameras I have combined 2 images (640 x 480 each) with jit.glue and separated them on the receive computer with jit.scissors
    I have a lot of latency. My FPS drops down to 3fps on my second computer.
    Is that normal ?
    What I am doing wrong ?

      your matrix is just too big. Unless you are doing a lot of processing in the sending computer before you send the matrix on, you aren't going to gain anything by trying to pass so much data over a network, and you may even lose. At 1280 x 480 1-plane matrix is about 614 kB. which is a lot to push over a network 20+ times a second.
      Your only real options are to pass less data, and use the best hardware you can get -- gigabit router, wired connection. I can get about 24fps on a 1-plane 320x240 matrix using the hardware described above, but that is only 76 kB/frame, passing data between 2 new Mac minis.

      Thank you Mattyo
      I guess I'll have to cut down on certain things !
