1. Visit profiler.el and go to this function:
(defun profiler-cpu-profile ()
"Return CPU profile."
(when (profiler-running-p 'cpu)
(profiler-make-profile
:type 'cpu
:timestamp (current-time)
:log (profiler-cpu-log))))
Position cursor on "profiler-make-profile" and type "C-h f". Emacs
pops up a *Help* buffer saying:
profiler-make-profile is a compiled Lisp function in `profiler.el'.
(profiler-make-profile &key TAG VERSION TYPE LOG TIMESTAMP DIFF-P)
This function has a compiler macro `profiler-make-profile--cmacro'.
Not documented.
Click on the "profiler.el" link in the *Help* buffer -- Emacs
displays an error message saying "Unable to find location in file"
2. How to interpret the "memory profile"? What does a line such as
this in the profile mean:
- execute-extended-command 973,272 20%
How were the 973,272 bytes counted, and what are they 20% of? The
ELisp manual, where this facility is described, does not explain
how to interpret the profiles, and neither can I find anything
about that in the doc strings.
3. Displaying a memory profile after several minutes shows clear signs
of overflow:
- command-execute 151,652,741 0%
- call-interactively 151,650,661 0%
- dired-x-find-file 44,210,847 0%
- find-file 44,210,847 0%
- find-file-noselect 44,209,884 0%
...
- normal-backup-enable-predicate 7,091,148 -1%
- file-truename 7,091,148 -1%
- file-truename 5,910,436 -1%
- file-truename 4,729,872 1%
- file-truename 3,549,420 1%
- file-truename 2,369,208 0%
file-truename 1,179,936 0%
etc.: I see no percentage numbers except 1%, 0%, and -1%.
