Emacs 28 with native-compilation / gccemacs
 

Just a heads up that native compilation has been merged into the main tree (project here), and I believe it will be the default for Emacs 28. I've not tried it yet, but I hear that it will bring significant performance boosts. This paper claims speed improvements "ranging from 2.3x up to 42x with respect to the equivalent byte-code, measured over a set of small benchmarks". Awesome! :hattip:

Yes it's really fast, i tested it for a while with a local build.
However Im not sure it will be the default build option, as i understood only the compilation flag is made official from experimental. I hope it's not the case though.

Am I missing something? Because I get

For gccjit, build gcc with

Praise the light! It is indeed faster(especially noticeable if you use lsp-mode)

I doubt that, cause LSP mode uses external LSP server and the productivity of the overall system depends upon the speed of the server + communication delays.

Only native Emacs functions will work faster.

---------------------------------------

It would be great to have Emacs with native compilation in the new Slackware 15!

You mean the 200% speedup was a lie ? :( https://emacs-lsp.github.io/lsp-mode...ance/#gccemacs.

I attributed the poor performance of lsp to my 10 years old laptop

200% speedup means that the compiled elisp code runs 200% faster then the previous bytecode. It is only related to native Emacs functions. Here we have the following scheme: (Emacs) <- (Communication line) -> (LSP server).


LSP server won't run faster. And there are still communication delays. There will be a speedup, but not 200%.
