This might not be the exact forum for this; but how do i calculate bandwidth consumption for a X-terminal?
Work with it, watch the meter. It is usually between 4 and 12 Mbit/sec per client (in 1024x768x24/32), depending on how much you do. But the more X terminals you have, the more CPU, RAM and network power you need in one box
I am planning a "blackbox" and to use a remote Multi Head X-terminal to be able to keep my working space as quiet as possible.
www.sun.com/sunray/sunray1/ - 15 W power consumption, no fans. Work with Linux too.
My idea is to use 3 or 4 (yes three or four!) 1600x1024x32 bpp wide screen monitors and run them as a "dumb" terminal over the network.

You asked that before.
I want to be able to use the machine as a workstation with full frame video capability on one monitor.
GL is usually painslow over network, don't try.
I read somewhere that a 640x480@24 fps MPEG-2 file is using some 45 MB in bandwidth.
Fact is, that just does not work well. Playing a VO: [x11] 720x480 => 720x480 Planar YV12 using mplayer results in like 4 fps and 53 MBit/s network load (IOW: no good). Though, I ran that through ssh -X, so encryption on the server side is a bottleneck.
What would a 1600x1024@24 be? (if my math mpu still is functional i estimate some 2.5^2 = 6.25 times 45, which would be some 280 Mb/s)
No. Don't. Watching videos over X terminals is more painful than any low-grade (like NV4) local graphic card. Jan Engelhardt --
