I have compiled straight from source on the feature/native-comp branch, and it works noticeably much faster. I am actually scared of going back to the regular Emacs, as I may find it way too slow.

I am not sure how much it is from native Emacs, as when I did this, I also enabled all the other recommended optimizations from lsp (increasing the gc threshold early in the config, installing and compiling with native json support etc.)

As far as I know, the latest branch has all the necessary flags enabled, so you can just do

    ./autogen.sh && ./configure --with-nativecomp --with-xwidgets --with-json && make -j4 && make install

after you installed the dependencies and cloned the Emacs repo (--with-nativecomp may actually be set to default now in this branch). You also need a very recent version of gcc, as the libgccjit is somewhat new, and it may err on the compilation process.

I'm running the "native-comp" (libgccjit) branch daily since months and months now: not a single problem here and I've got quite a "heavy" config (thousands of lines of custom config and all the usual suspects: magit / org-mode / lsp / cider etc.).

And it worked? Worked on the first try for me (on the Debian distro).

I was somehow expecting lots of problems (because it's one heck of a change) but it really all just compiled and worked perfectly fine.

I am. I honestly don't notice much of a difference, but at the same time I keep seeing deferred compilation warnings for plugins I have added via straight.el

I've been using https://github.com/flatwhatson/guix-channel to manage it. I don't recommend trying the Pure GTK+ stuff yet though; some context menus don't seem to work. Specifically, treemacs rename seems broken with PGTK.

Yes, it's pretty solid running Doom Emacs. There's a handy macOS build script/helper:

Over half a year now, as a daily driver. Personally on Ubuntu, at work on WSL (Windows Subsystem for Linux) - which I then x-forward to an VcXsrv on Windows.

Works pretty much flawlessly, and it's much snappier on some of the workloads I put it through - like big collections of big Org Mode files, or viewing (and fontifying) large files.

Running the native-comp + wayland copr on fc32 for about a year, whithout any problem. About 3x faster.

I've just tried it on macOS, built by this tool: https://github.com/jimeh/build-emacs-for-macos

Unfortunately it keeps locking up my entire computer so might not be a goer just yet.

I've been using it for a few months on wsl and it's been great. I'm using the Nix package and have run into only a couple of minor issues.
