I just wanted to share a blog post I just wrote, comparing a simple concurrency pattern I’ve often used in Go, which I tried to implement in Crystal: https://rillabs.com/posts/crystal-concurrency-with-easier-syntax-than-go I posted on HN as well, although doesn’t seem to have taken off there (yet)…

Nice! The equivalent of defer is begin/ensure. Aha, thanks! Gotta check that! EDIT: Updated the post with “ensure” now, thanks! :slight_smile:

This is fantastic, I love when people show the code for comparison. It really highlights the differences in ergonomics between the languages. I did the same when comparing Crystal to Rust and, even though the ergonomics weren’t the point of that post, people still mentioned it a lot. :-D One of the…

Thanks for kind words :slight_smile: And thanks for pointing out the compiler flags etc. Yes, for performance comparison, I’ve been using those. Updated the post now, to clarify that, should have done it from the start for sure. That is a very interesting post comparing with Rust as well! Didn’t e…

I don’t think Crystal can beat Go here. I suspect a lot of time is spent in the runtime, sending stuff through channels, doing context switches, etc. Go is really optimized for that stuff, at the register level. Out of curiosity: why are two fibers or goroutines even needed here? Reading from a fil…

FWIW its --release . Notice the two - . I don’t think it would work with just one. Fixed, thanks!

[image] asterite: Out of curiosity: why are two fibers or goroutines even needed here? Reading from a file will never block so you can just read from it and parse it as you go. I guess it’s just to demonstrate the usage of fibers and channels? Exactly. Although I have been playing a lot with …
