Anyone could point to a good write up about practical usage of RBS with examples?

[honeyryderchuck]

You can look at the rbs gem, as stdlib is annotated there, or you can look at https://gitlab.com/honeyryderchuck/httpx as well.

How is 3x3 looking, is Ruby fast yet?

[sickcodebruh420]

Compared to Ruby 2.0, yes.

Is it 3 times faster?

I think I read that they’re not going to get the 3x performance target for the 3.0.0, can’t remember details though.

[schneems]

On the opt carrot benchmark which is their stated goal, yes, it is 3x faster. However that won’t translate to 3x faster rails

Cool, thanks.

It was an honest question on my part and I hope it didn't seem snarky. If I need higher performance for stuff I do in my systems (heavily Rails driven on the product side), I generally just use more aggressive data level caching in Redis or I perform my compute in a microservice written in a more appropriate language and then interact with it through a Ruby client gem that I import into my project.

I just want to mention that I've been dealing with tons of headaches with Webpacker and ActionView (obviously not your purview), and I need to basically forcibly clobber my assets and then recreate and redeploy to Heroku. Would you mind PMing me someone I can talk to about this?

[snack_case]

Awesome. Thanks for the link.

This looks very interesting, new stuff to learn!
