Slows down loading, even of text files
I was noticing that my file loading in emacs had become quite slow. It seems that treesit-auto mode may be part of the issue.
The following is my benchmarking result:
(global-treesit-auto-mode 1)
(benchmark-run 1 (find-file "x.txt"))
=> (1.84767 0 0.0)
versus:
(global-treesit-auto-mode -1)
(benchmark-run 1 (find-file "x.txt"))
=> (0.047460999999999996 0 0.0)
It would be nice if this were faster. Is there a workaround, at least, where we can only enable this for prog-mode buffers?
Thank you!
Thanks for making this issue, I have been waiting through multiple seconds of latency to jump between wikilinked markdown notes, and I had no idea which package was at fault until I saw this and tried disabling it. I'll be sure to manually configure my treesitter modes from now on and avoid this package.
Since macOS Sequoia, I notice every file I open takes about 2s and the CPU profiler shows that most of the time is spend in treesit-auto--set-major-remap in after-find-file:

Jeremy Friesen suggests to cache the lookup of the expensive treesit-language-available-p call:
https://github.com/jeremyf/dotemacs/blob/75410e2f56273b2be4abf10d0d72627ec4ad6a85/emacs.d/init.el#L5176-L5197
That works extremely well for me.
So as a suggestion, treesit-auto--set-major-remap could also employ a cache maybe
I see the same. I mainly notice it when using consult-ripgrep and navigating through candidates. (global-treesit-auto-mode -1) makes it immediately fast, again.
