cryload is a powerful, fast, and practical HTTP benchmarking tool for stress testing APIs and web services. Built with Crystal for high performance and low overhead.

Impressive benchmarks. Reaching 1M msgs/sec on a 2 vCPU instance is a great showcase for Crystal. As a Crystal core member, I've always seen LavinMQ as a prime example of performance-oriented engineering, especially with how it handles I/O and minimizes syscalls to get the most out of the hardware.

If you want to see Crystal's concurrency and type system in a serious production environment, this is the project to check out. Kudos to the LavinMQ team for their work since 2020.

Hi everyone,

I wrote the original "Why Crystal?" blog post back in 2015 when Crystal was just v0.9.1.

Ten years and many versions later, I am revisiting that post to analyze the road to v1.20.

If you are interested in how a language matures from a syntax experiment to a high performance standard, this one is for you.

Using Crystal with Kemal extensively at our platform: Açık Türkiye https://acikturkiye.com/

Nope, this is way before that talk

There's also a Chinese version at https://cn.crystalforrubyists.com It's not updated for a while though happy to have your PRs :)

Thanks a lot! Happy to have your PR :) https://github.com/sdogruyol/crystal-for-rubyists-en

Crystal is a Ruby inspired compiled language, it's blazingly fast with a very low memory footprint. It uses LLVM for emitting native code, thus making use of all the optimizations built into the LLVM toolchain.

~100k LOC in Crystal? that's pretty amazing

I'm the creator of Kemal, glad to see that you're liking it :)

We use Crystal at RainforestQA to replace our heavy-load / slowish Ruby microservices. It's been great so far and we love it. We're also increasing the adoption to Crystal inside the organization.

Also Crystal has a dedicated a wiki page for production users

Even though it's experimental I've successfully compiled Kemal with multi-thread support. The throughput was OK. It's promising and will definitely help CPU bound apps :)

Here's a great blog post about Kemal and Websockets :) http://kemalcr.com/blog/2016/11/13/benchmarking-and-scaling-...

I've been using Crystal for more than 2 years have some projects in production. Can't wait for 1.0 :)

Great post! I'd be happy to hear about some numbers about performance and resources.

Crystal is great! It's still being under development but there's not many breaking changes after 0.20.0+ and it's getting smoother day by day. Parallelism and Windows support are on the way. BTW feel free to join the superb friendly community on Gitter https://gitter.im/crystal-lang/crystal :)

This is a great article. However I'm curious how much work is actually needed to get a seamless / native Crystal experience on Windows?
