> - YJIT has made Ruby fast. Like, _FAST_

Then I pray with all my heart that GitLab moves to it, because that's one of the major complaints I hear about folks who use their web interface. Even while I was visiting the site to look up whether their main repo had a .devcontainer folder in it, I could just watch all the stupid ajax-y shit spin endlessly in what is conceptually a static table (sure, it changes per commit, but they're not a stock ticker platform)

OT1H, I know, I know, "MRs welcome" but OTOH as a ruby outsider getting the dev environment up for contributing to them has been a lifelong struggle. Now that Rubymine has support for .devcontainer maybe it'll work better

I'm not saying GitLab is poorly designed, but a poorly designed website will be slow on the fastest of languages or frameworks. It's not necessarily a Rails or Ruby problem here.

YJIT does make Ruby fast, but that doesn't mean it makes _Rails_ fast. (yet) At least dont expect multiple times improvements.

Hopefully in the future.

There's plenty of reports of YJIT lowering real world Rails applications latency by 15-30%.

There is also plenty of perfectly snappy Rails applications out there. People need to stop blaming the framework...

Well, a lot of those pages have Vue application running on them.

GitHub has always been fast for me.

I have wondered about that, and I'd guess the thing you (and the sibling comments) pointing out about how GH seems to take an html-fragments approach versus GL opting for the more traditional(?) AJAX one probably does matter a great deal on the end user experience

Regrettably, since GH doesn't develop in the open, it's hard to have an apples-to-apples between the two in order to know if GH has some really, really tuned RoR setup, or it literally is just a matter of "don't be cute" when sprinkling every JS trope known to man upon your web ui and if GL one day cared about their page load times, they, too, could be quick without needing a RoR nor RVM upgrade
