gcmh VS build-emacs-macos

cf. https://github.com/emacsmirror/gcmh (the author's [=Andrea Corallo's] Emacs package "GCMH - the Garbage Collector Magic Hack")

A lot of people use way higher values than 800 KB without any problems. As a matter of fact, I've been using 256 MB for a very long time, haven't noticed any issues with it. So I wouldn't call 1 GB madness, it can be perfectly fine in some cases, especially if one uses gcmh, so it has a high chance that GCs will happen when the user doesn't interact with emacs (I also setup emacs to do GC when emacs loses focus. This means that GC pause is invisible most of the time for me). I strongly prefer very rare, short GC pauses than microstuttering all the time. Also, some operations apply a lot of pressure to the memory system, and do hundreds of GCs with the default setting, so most of the CPU time is spent in the GC when these operations run. Increasing gc-cons-threshold makes such operations much faster which means less pauses.

One possible solution is to switch to a LSP approach. You should also take a look at the garbage-collector-magic-hack package: https://github.com/emacsmirror/gcmh

If you experience some lag, my first advice would be to install the GCMH package. It basically changes the garbage-collection rules to ensure that most garbage collection will happen in small bouts while Emacs is idle. After installing it I've never had my Emacs lag on me. This wouldn't address the retina-display issues you mentioned, but I've never experienced those with emacs-plus.

I've seen gcmh recommended as a library that configures the garbage collector for you. Not sure if it is truly a "one size fits all" solution though.

I’d add that for 1) beacon is a good package. For 2), this may be an issue where you have multiple emacs configuration files. This is a serious problem. 3) be patient, and use the magic GC hack. To add to that, you should probably set the GC threshold to be high. 4) projectile? 5)emacs -nw.

Though I don't love Ventura, running Emacs on MacOS has never really been a problem for me. It's also very easy to build Emacs. You can use this shell script if you like: https://github.com/mclear-tools/build-emacs-macos. I also list there a bunch of other build scripts from other users. Just as easy as homebrew really, with a lot more control (e.g. you can build whatever version of Emacs you like, at least back to 22).

You might find this shell script for building emacs useful. https://github.com/mclear-tools/build-emacs-macos

I build emacs myself from the master branch on an M1 and Monterey and don't see this issue. So it might be something either with your config or with that specific build setup.

Here's the build script that I use. It is pretty dead simple. https://github.com/mclear-tools/build-emacs-macos

Hi all -- I've put a repo on github for building emacs on macos. There are several other such scripts available, but I've tried to make mine as simple to understand (I'm not a programmer) as possible (or as possible for me...). It currently works well for me but YMMV. Of course, I realize that there are a million ways to shave this yak, so I'd be curious if anyone has suggestions for improvement (though I'm also looking to keep things as simple as possible). I hope this might be of some use to people.
