crystalruby VS Programming-Language-Benchmarks

Recently, I came across an article titled “Ruby might be faster than you think” In this article, John Hawthorn revisits the code snippet from the CrystalRuby README and optimizes it to show that Ruby is just as performant, if not more, than the alternative presented by CrystalRuby.

It is common to call C functions from Ruby or Crystal. It's interesting to know that there are alternatives to bridge these two languages that share the same goal of writing beautiful programs, using a similar syntax. The mentioned crystalruby gem allows interfacing Ruby programs with Crystal, and the shard anyolite allows calling Ruby programs from Crystal.

Another ruby/crystal project coming hot on the heels of crystalruby[1].

I can see that both have different use cases but it's interesting to see the two approaches.

Crystal and Ruby are two wonderful languages, each with their pros and cons. Crystal's performance and low memory footprint is hardly contested, and can further be studied in the benchmarks of language and compilers (but be critical about benchmarks!).

The benchmark available at https://programming-language-benchmarks.vercel.app/ demonstrates that Golang stands out as one of the most memory-efficient languages presently available. This achievement is attributable to several inherent features of Golang, such as its static typing, robust garbage collection system, and the inherent structuring of data within the language. These traits collectively contribute to Golang's exceptional efficiency in terms of minimal memory consumption compared to other languages.

I found Zig implementation of json parsing is interesting. The code is free from hidden control flow !.

I think https://programming-language-benchmarks.vercel.app/ is a good starting point to compare languages and compilers, also implementations are optimized for the specific language so you don't end up with a poorly ported c++ implementation in rust and wonder why it performs so bad.

It varies a lot depending on what the code consists of, but if you want concrete numbers for certain benchmarks, this site might be of interest: https://programming-language-benchmarks.vercel.app/

There is not "one real" benchmark. In the end, all you can do is test languages for a specific feature / purpose. You can see how many different suggestions people have here, and here (I think) you can see the difficulties of comparing languages. That site uses quite a lot of algorithms / problems with multiple inputs, single and multithreaded, with different optimization flags (where applicable) and so on paired with different languages, and it's a mess. Sometimes one language is on top, sometimes another. (I mean, python will very rarely beat pure C, but I wont rule out that someone already created an edge case just to refute exactly this point)
