[Colton Idle]

I'm having a perf issue in IntelliJ/AS with larger projects with kotlin.

If I have

val asdf = "asdf"
        when (asdf) {
            "abc" -> {
            }
            else -> {
            }
        }

and then comment out the first line, it takes about 15 seconds for the when statement to show as invalid (the asdf var is underlined in red).

How would I get a trace in order to file a bug for this? How can I help JB with this issue?

[Alexey Belkov [JB]]

Please file an issue at http://kotl.in/issue with a CPU snapshot taken according to https://intellij-support.jetbrains.com/hc/en-us/articles/207241235-Reporting-performance-problems. Thanks!

[thanksforallthefish]

there is https://youtrack.jetbrains.com/issue/KT-32378 not sure your problem is the same

[Alexey Belkov [JB]]

In general, please avoid adding more snapshots etc. to already existing issues. It's really hard to tell if it's a duplicate or not, so it's better to always create a new issue.

[Alexey Belkov [JB]]

By the way, if you're using Kotlin plugin 1.3.70, try to disable the new inference in IDE (https://youtrack.jetbrains.com/issue/KT-32378#focus=streamItem-27-3551507.0-0), it may help.

[Colton Idle]

Already had the new inference turned off.

@Alexey Belkov [JB] are you saying I should follow the section that says "Profiling Slow Indexing". I didn't know that my problem was "slow indexing", but that's the only section that mentions cpu snapshots.

[Alexey Belkov [JB]]

No, I mean the following section:

The CPU usage is high or IDE is slow

If you can continue working with the IDE, but it feels slower than expected or CPU usage is high read below

@Alexey Belkov [JB] thanks. I could have sworn that it said "The CPU usage is high" and nothing else. 😄
