The main questions for me is how Kotlin IDE support ended up being so unbearably slow. Why there were no regressions to notice performance degradation? Even if the new compiler is super-fast and fixes IDE performance, what stops it from becoming super-slow again a year later :man-shrugging:

This year, a dedicated performance engineer joined the Kotlin IDE team. One of his tasks is expanding the IDE performance (regression) tests: <https://github.com/JetBrains/kotlin/tree/7fede87825cf42aa4930ab96a6769008c92cc3e9/idea/performanceTests>
