Interesting, I got the impression that the problem was being restricted to a single thread. “being single-threaded, couldn’t process operations in parallel”.

Wonder what the article would have said in a parallel universe where the problem was migrated to something like the Akka framework on the JVM?

I'd imagine that if they had switched from Node.js to Akka they likely would've solved some of their issues dealing with single-threading - while I like Node.js I think the point where performance matters more than feature iteration it should be refactored into something that suits your domain better.

That being said, they mention being turned on to low resource usage specifically because of garbage collection issues and resource overhead. While the JVM is lighter than the Node.js runtime when considered across multiple cores I think that's just going to give them more runway to tackle the underlying problem they were still having.
