It depends. There is less latency in the IDE due primarily to better GC (just as the article describes). I think the speed is better too on things like indexing the code base, but that could depend on your computer. I'm running on a 32core high end AMD system with lots of RAM, and I increase the heap setting in Intellij to 4G, etc. I think the IDE is subjectively better.
We run all our production applications on JDK17 too, which is why I push to run everything on 17.
