As long as you are doing all that you might as well make some of the info graphic (bar charts or speedometers, etc.) and on and on. Funny you should mention X! We've recently got an AViiON and have had nothing but frustration getting help from our DG representative. We have concerns over X performance and the best they can do is say "tune your application" instead of helping us tune the installation. As a result we get our applications running faster on our SUNS and DECS, but are left with slightly faster but still much slower on the AViiON X applictions! Aaaargggg! Ok. I'm calm. This is my first time in comp.sys.m88k so please excuse me if these issues have been raised before. We want to run a particular X application we have developed on an AViiON. X applications seem to run slowly. In fact, everything seems to be slower on the AViiON than on my SPARCstation 1+. We expected better. Today I ran the X application "xengine" on 3 platforms. I displayed the image on the console and on a remote display (not at the same time). Here's what I found: \Display | SUN4* AViiON** DEC*** \ | CPU \ | -------------------------------------------------------- | SUN4 | 257 68 656 | AViiON | 225 70 630 | DEC | 225 68 715 *: greyscale SPARCstation 1+, SunOS 4.1, 16MB, MIT X11R4 **: colour Data General AViiON, DGUX 4.2, single CPU 16MB, DG supplied X11R4 ***: DECstation 5000 with colour graphics accelerator, Ultrix 4.2, 24MB, MIT X11R4 What I deduce from the above data is that for xengine, the AViiON's X server is nearly 3 times slower than on my Sparc and nearly 10 times slower than on the DECstation described above. The DECstation is fast I admit, but the difference in speed between the Sun and DG is very large. I won't speculate right now, but I'd sure like to get some feedback on what is going on. As I said above, our local DG reps have been very unhelpful. Any comments would be appreciated. Shaun (ssmith@mprgate.mpr.ca) -- Shaun M.
