As should be apparent to those interested, running programs like
prof or gprof on an X application just doesn't work, or at least if
its done as outlined in the man pages.
Has anyone succeeded in profiling their X code?

(We're not optimizing the X libraries.) 3) After running our program, I run prof or tcov. Here's the beginning of the last prof report I ran (in this case on an HP 825 running HP-UX 7.0): %Time Seconds Cumsecs #Calls msec/call Name 96.033663.9133663.91 $$mulI 0.9 302.2433966.15 _mcount 0.6 194.0734160.2241402178 0.00 memcpy 0.1 43.2334389.89 1817682 0.02 BPLResolveToValue 0.1 38.0034427.89 227434 0.17 BPLExecutionSetup 0.1 37.8534465.74 4164918 0.01 dbInCheck_ 0.1 29.0634524.66 7043351 0.00 RSTKType ...(zillions of lines deleted)... The routines probably won't mean much to you (they had better not :-). I guess I don't understand what the problem is. I'm no prof guru, but I have used the data provided by prof to write more efficient programs and that's what counts to me. I suspect that if you were more specific about your problems and the system you are using, then you might get more help. Have fun, -Eric -- Eric F.
