Guys, do anybody else feel that IntelliJ Ultimate is pretty slow to do it's things? Sometimes it takes 2~3 seconds to find out that a class isn't imported

Do you feel like it's related to the Kotlin plugin? Then please report an issue to http://kotl.in/issue, ideally with a sample project, steps to reproduce and a CPU snapshot taken as described in https://intellij-support.jetbrains.com/hc/en-us/articles/207241235-Reporting-performance-problems If it's more of a general IDEA problem, then please report the same to IDEA tracker: https://youtrack.jetbrains.com/issues/IDEA. Thank you.
