And as I have said before but worth repeating again, Rails is perhaps the only open source framework that is being battle tested in development at scale. It may not be the fastest ( or in fact quite slow ), but I dont think you could find similar testing being done and Deployed at the scale of Github on any other framework.

I wonder if Eileen Uchitelle will bring this practice to Shopify as well? Edit: It seems [1] Shopify is also running on latest Ruby and Rails version as well.

Web is not CPU bound, it's memory and network bound. Rails can run huge traffic perfectly fine if you know how to code for performance (e.g. caches, async with Kafka etc.) Ruby had also pretty significant speed improvements in the last years.

This! Having served multiple thousand users at once from a cheap $15 DO box the thing about rails performance is just how you built it.

The tools are there, you just need to understand and use them.

There's at least Spring.

It's been a very very long time I touched anything Java so excuse my ignorance. I know there are many Enterprise, internal Web Apps that uses Spring. But are there any web companies built their SaaS or Consumer Web App on Spring, that is at the scale of Shopify and Github?

Aliexpress and Udemy come right at the top of my mind. But there are quite a few more. (several German web-sites like Trivago). Spring Boot is used more outside the U.S. - Java is respected more in the rest of the world.

Most companies at that scale don't use a single framework or even language but there's probably more Spring at Amazon than RoR at GitHub, Stripe and Shopify combined.

Stripe doesn't use Ruby on Rails, they have a framework developed in house

I couldn't immediately locate it, but there was a famous example of an Amazon property leaking its Java stack trace but since I can't locate it I also can't swear it contained springframework classes

Pretty sure Netflix uses a ton of Spring.

It's one of the most common frameworks in the industry across languages.

Yes, we’ve been doing this at Shopify for quite a while now.

The Spring framework is the 800-lb gorilla comparison and I'd be surprised if Ruby was within an order of magnitude of Java.

That's because for business web apps, the code execution speed is a more minor factor compared to other latency issues.
