> Since V8 implements a stop-the-world GC, new tasks will inevitably receive less CPU time, reducing the worker’s throughput
But there is this Google blog post vom January 2019:
https://v8.dev/blog/trash-talk
> Over the past years the V8 garbage collector (GC) has changed a lot. The Orinoco project has taken a sequential, stop-the-world garbage collector and transformed it into a mostly parallel and concurrent collector with incremental fallback.
So I guess they used an older node.js version. The current LTS version is 12.x and it is from around the middle of this year.

PS: If the blog author reads this, there is an accessibility problem with the Google-hosted inline images. If I try - without ad blocker - in an anonymous window I see none of the inline images. Logged into Google with my own account I can see some but not all the images. Apparently which images I can see depends on being logged in to my Google account? I also tried IE Edge just to see if the browser makes a difference - no inline images visible there either.
