Re: [Bug: 21.5-b28] performance on aix, cpu hog, another session gprof output

Thomas, Thanks for going to the effort of collecting this profiling data. It gives us some interesting information. 2008/3/11 Thomas Mittelstaedt <T.Mittelstaedt(a)cadenas.de&gt;: [snip] So the top 48 time hogs together consume a grand total of 1.00 seconds out of 97.87 seconds of execution. Your other profile was similar: out of 56.55 seconds of execution, the top 43 collectively consumed 0.73 seconds of execution. This indicates that the performance problems you are seeing are not occurring in the profiled (i.e., XEmacs) code. We appear to either be triggering a performance bug in some library, or using some library in a suboptimal way. In either case, this is as far as a profiler is going to take us. I'm still curious about the large number of kioctl calls in the truss output you showed us earlier. Do you know why that output did not start with the launching of the XEmacs executable? Can you get us truss output that does start from launch? I want to know what file descriptor is the target of all that manipulation. It may be a red herring, but I think it's worth checking out.
