EAP means early access program.

Really excited about the speed improvements they promised for this version. Even on a machine with 16GB RAM and increased max. memory for the JVM the UI just feels too slow.

> With v2020.1 EAP we are fully moving to JetBrains Runtime 11 (JBR11), and will no longer distribute builds with JetBrains Runtime 8 (JBR8). Please note that all the IntelliJ IDEA 2020.1 updates both in the IDE and the Toolbox App are coming with JBR11.

Does this mean I need to have JDK 11 installed too? We're still using JDK 8 because Spark 2.x doesn't support JDK 11, and having multiple JDKs sounds like a pain.

edit: nvm. Looks like JBR doesn't have a JDK dependency.

I don't see anything about performance improvement in this post.

Btw how much ram have you given to intellij?

Do you have a link for that? I Ctrl+F'ed the page and only found one mention of speed in a user comment.

No, they include their own JDK with the installation where the IDE run on.

I don't think so. It's just the internal one they use.

Wonder if they are using the Graal JIT compiler that comes with JDK 11...

Easy fix: replace the the existing GC line with

  -XX:+UnlockExperimentalVMOptions
  -XX:+UseZGC

and enjoy no more visible lag spikes.
