Rosetta is fast unless any kind of JITed code is involved. A lot of Java development is happening with tools written in Java for the JVM which is relying a lot on JIT compilation.

The JetBrains IDEs were bordering unusable under Rosetta. They would speed up over time as Rosetta did its work, but it was multiple tens of minutes of slow as molasses until things got better and after each IDE restart you were back at square one.

Thankfully, JetBrains released updates to their products to run on a bundled ARM JVM very quickly

Very true! I received my MacBook on November 23rd 2020 and Jetbrains released an ARM optimised version of IntelliJ December 30th 2020. I may have used an EAP version some days/few weeks before release. https://blog.jetbrains.com/idea/2020/12/intellij-idea-2020-3...

I remember that first month as being very painful to use the IDE. It was really dramatically slow.

Discord was also pretty bad under Rosetta. Last I checked the Canary version was built for Apple Silicon and ran much better, though I'm not sure if that's made it to the stable release yet.
