Intellij IDEA 2023 unusably slow on non-M1 Mac

I am using a 2019 MacBook Pro and have been a long-time user of IntelliJ IDEA. However, the 2023 version is extremely slow when attempting to perform any task. I have tried increasing the heap size to 4GB and 8GB, but IntelliJ still uses more than 1000% of the CPU and runs out of memory. After reverting back to version 2022.3.3, it runs smoothly with a 2GB heap size, and I can quickly close project windows and type smoothly in the terminal while a project window is starting.

Is there anything I can do to improve the performance of the newer version? I don't want to remain on 2022 indefinitely. Since the issue is unclear, I am unsure how to look for relevant YouTrack tickets.

This has finally been fixed in 2024.2, currently available via the Early Access Program.

The source of the issue was JetBrains Java Runtime, which has been upgraded v17 => v21. Blog post: Switch to JBR 21

Please Tell the detailed version number of the IntelliJ IDEA.

I'm work fine both in M1 and Intel MacBook Pro.

IntelliJ IDEA 2023.1 Preview -> Build: 231.8109.175

Each version of IntelliJ IDEA has macOs dmg for Intel and macOs Apple Silicon dmg for the M1. Make sure do not install the wrong dmg.
