Does this means that it will likely be in a release prior to version 28? I'm not too familiar with Emacs release scheduling.

[_k9eq → anaerobicover]

No, if it has been merged into the master branch, it will be released with 28.1.

Native compilation will need to be manually enabled on init.el or is already enabled by default?

[rgrmrts → nahuel0x]

Currently (with the native-comp branch) you have to enable it in your init.el, I assume that behavior will remain.

E.g.:

  (setq comp-speed 3)

[bjoli → rgrmrts]

Use comp-speed 2 for Emacs as a whole though. 3 will break some semantics of the language if I understand correctly.

[rgrmrts → bjoli]

Good to know, thanks! Hasn't bit me yet, but my config is fairly light.

From an Quick google I was unable to find any benchmarks. Does anyone have any anecdata?

[rgrmrts → bjoli]

I started using the native-comp branch a few months ago and have had no issues. As for performance, I haven’t benchmarked but things are noticeably faster and smoother. I’m on macOS and my main issue was the display going blank for a few milliseconds, and I’m no longer seeing that so a huge win in that regard! General search and completion seem faster too

There are some benchmarks here (elisp-benchmarks package): https://akrl.sdf.org/gccemacs.html

Feels like 10x faster
