![]() ![]() Even more of my users run from remote offices using NX (which is still really X). However, it does not really matter, because for any sort of WAN connection we have NX. He was working on eliminating those unnecessary round trips. According to, I believe, Keith Packard some years ago (who had worked on LBX previously), approximately 90% of the round trips were actually unnecessary and an artifact of the then current implementation, and not inherent in the protocol itself. Start an application like Firefox and watch the lights. The most dramatic way to demonstrate standard X’s sensitivity latency is to set up a ppp connection over an external modem. 10baseT has essentially the same latency as 100baseT. It is latency which kills the standard (non-NX) X protocols. ![]() X actually does quite well over limited bandwidth. People have a tendency to think in terms of bandwidth. X works about as well under 10baseT as 100baseT. Therefore, over the internet is performs poorly, while RDP shines when running over the internet.Īctually, I did not directly address this issue in my previous response to tyrione. Xvideo on the Xserver takes care of RGB conversion, deinterlacing and scaling.ĭoing this with RDP works very badly, because if you watch full-screen at 1280×960 the RDP server needs to send which is even doubtfull on a 100mbit network.įurther, note that X is not so much bandwidth but more latency limited. Watching a DVD with Xine on a remote Unix server, for example, works rather well because a PAL frame is just 720×288 pixels 50 times a second. RDP can only do 2D RGB screen updates (which it does this very well), but cannot do YUV, 2D rendering (Xrender) or 3D. If the application is well written (properly uploads all its images to the X server and reuses them), X still rules over a 10 mbit network compared to RDP, because you have an Xserver with all extensions activated. Move back to 10baseT or 10base2 and compare it’s performance in a network environment next to OS X and it’s WindowServer approach. 100BaseT is the baseline for no-one to complain. ![]()
