Increasing time of running benchmarks is just a symptom.
The real issue I am experiencing is that re-search-forward becomes
slower as I keep using Emacs. `garbage-collect' helps, but not in a long
term.
Basically, running
M-: (benchmark-progn (goto-char (point-min)) (while (re-search-forward yant/re
nil t)))
- right after starting Emacs is taking 3-4 seconds.
- after several hours -- 10-20 seconds
- in Emacs 28, <1 sec.
Markers may or may not be a problem. If they are, it is not necessarily
related to markers created when I run the benchmarks. May also be some
markers created during the Emacs session.
