Re: [Bug: 21.5-b28] performance on aix, cpu hog

Well, I managed to build xemacs with -pg on compile and link. Attached is the output of gprof, which is the one the system provides. In that sample session, xemacs ran at more that 40% cpu. I also switched window managers from wmaker to icewm. But still, xemacs would consume a lot of cpu in the (large) range of 20-40%. Hope this helps. thomas Jerry James schrieb: call graph profile: The sum of self and descendents is the major sort for this listing. function entries: index the index of the function in the call graph listing, as an aid to locating it (see below). %time the percentage of the total time of the program accounted for by this function and its descendents. self the number of seconds spent in this function itself. descendents the number of seconds spent in the descendents of this function on behalf of this function. called the number of times this function is called (other than recursive calls). self the number of times this function calls itself recursively. name the name of the function, with an indication of its membership in a cycle, if any. index the index of the function in the call graph listing, as an aid to locating it. parent listings: self* the number of seconds of this function's self time which is due to calls from this parent. descendents* the number of seconds of this function's descendent time which is due to calls from this parent. called** the number of times this function is called by this parent.
