I had to use Google to discover that PXES is 2X ThinClient. I believe 2X uses RDP or NX, both of which are 'buffered' remote displays, meaning that on the server a local snapshot of the graphical display is kept in memory, and periodically the differences that have occurred on the display are compressed and sent to the remote terminal (this is also how the Sun Ray system works, too, I believe). This methodology has a couple of advantages: (1) on slow, high-latency connections such as the Internet or a slower WAN, the remote client will get much better performance, (2) the client can disconnect or lose their connection, but they can reconnect at a later time and the display is still there, since the display was present on the server at all times.
LTSP uses normal remote X11, which does not keep a display buffer on the server and has no native compression. This makes it very poor on slow, high-latency connections, and if the user disconnects or the connection drops, there is no way to restore the display; the user must login again. However, the primary benefit of LTSP is that X11 is virtually indistinguishable from a local desktop when running on a LAN, because there is no buffering to slow things up. RDP or NX are pretty snappy over a good Internet connection, but they don't get much faster when run over a LAN. Even casual users can distinguish between an RDP session and a local desktop (menus are not as snappy, scrolling is affected, video or flash animations are affected), whereas they cannot normally distinguish remote X11 from a local desktop for most non-game applications. -Todd Ashish Nabira wrote: > Hello All; > > May I know advantages of LTSP over PXES ?? > > LTSP requires NFS which pxes doesn't require.
