Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
From: Yikai Zhao <yikai <at> z1k.dev> To: bug-gnu-emacs <at> gnu.org Subject: 30.0.91; (documentation 'pcase) can take several seconds Date: Sat, 12 Oct 2024 16:02:04 +0800
When `lsp-mode` is loaded, `(documentation 'pcase)` can take several
seconds to complete.
Apparently, it would iterate over all defined pcase macros (N), and for
each of those, `help-fns-short-filename` would iterate over all items in
`load-path` (M). Total time complexity is N*M.
In my case, N is about ~400 (defined in lsp-protocols.el) and M is about
~100 (I think it's a normal case?).
This is especially problematic since the `documentation` method can be
invoked by eldoc, which affects the responsiveness during editing.
