By default dx caches to fill the available memory. This can be optimized by hand or you can try the optimize option in the VPE. A result of hitting the play button with the button in the upper left of the Sequencer is that after all the images are calculated, it will play from cache. If you are using s/w rendering, it will be images played back from memory. If you are using h/w rendering, it will be renderable geometry. The playback speed will depend on the speed of the platform, the size of the network, the size of the images/geometries, speed of the graphics card and X, amount of memory, etc. By default, dx will grab 7/8 or 3/4 (I don't remember which) of physical memory. Using dx -memory n, where n is in MB (memory + swap) will override this behavior.
Having said all of that, your environment may be such that DX may not play back fast enough. If you are just looking at an animation sequence, you could output an animation in miff, tif, etc. and use ImageMagick animate to play back, generate an animated GIF and use xanim, or generate an MPEG (although that raises other issues for playback).

Thanks. Yes, my data are on scattered points only. One more question. My movie is going a kind of slow, I mean the frame refresh is about a frame/sec. I have enough memory, how can I force Data Explorer to read and keep all the frames in the cash? Is it possible to play the movie faster i.e. 5 frames/sec? Thanks, Ted
