Does anyone know how the Turbo Graphics option affects X-windows performance on a Personal IRIS? (For applications running locally -- not across a network.) I've heard that IRIX 3.2 provides a big improvement, but I'm looking for all I can get. I'm already planning a 20MHz CPU upgrade -- any idea how much that'll help? Is X CPU-bound or graphics-bound?? Thanks! --Pete Poorman

Something that was recently pointed out to me was that you can improve the performance of X applications on Iris consoles by setting your DISPLAY to be "unix:0" rather than "localhost:0". Apparently, the latter causes some interaction with network daemons, whereas the former goes straight to work, so to speak.

In general, the CPU speedup will give you the greatest boost in performance. The Turbo graphics upgrade will help out applications that are drawing lots of lines or small polygons. Large polygons are slightly improved. Jim Bennett (bennett@esd.sgi.com)

Large polygons are slightly improved. How about picking? The reason I ask is we were planning on getting the GT upgrade for our 4D/70's, but discovered that picking was significantly slower with the GT upgrade (6 times slower with 3.0, 2 times slower with 3.1 -- we have 3.2 but have not ran our benchmarks yet). Now we have lots of 4D/20's that our users want to upgrade. Will the turbo upgrade slow picking down? -- Mike York Boeing Computer Services, Renton, Washington (206) 234-7724 uw-beaver!ssc-vax!voodoo!zombie
