10-15 second delay after ALT-TAB to IntelliJ

This seems to happen mostly when I ALT-TAB to IntelliJ, then click on a different file to edit.

Any suggestions would be very much appreciated.

Kind regards,
Eric

Hi Eric,
Take some CPU snapshots during slowdowns and attach them to a new IDEA issue that you create. JetBrains should look into it.

Hi,
You can switch off Sync on Frame deactivation in General settings.

Hi All,

When I ALT-TAB to IntelliJ, I usually have to wait 10-15 seconds before I can edit source or click on anything. Sometimes I can edit source in the last file I was editing when I ALT-TAB to IntelliJ, but when I click on a different file to edit, I have to wait 10-15 seconds.

I've experienced this with 6.0+ and I'm currently running 6.0.3 beta build #6117.

I've tried removing all plug-ins that I can do without. I've tried disabling code analysis. Does anyone else experience this as well? Any suggestions and what I can do to avoid this delay? We have other developers working in the same project who do not experience this.

Thanks,
Eric

Hi Maxim,

Thanks for the suggestion. I always have that option turned off.

These are the settings I'm running in idea.exe.vmoptions right now:
-Xms92m
-Xmx386m
-XX:MaxPermSize=99m
-ea
-server
-Dsun.awt.keepWorkingSetOnMinimize=true

I added keepWorkingSetOnMinimize this morning to see if that helps. I also noticed that my JDK_HOME was set to JDK 1.4, I set it to 1.5. Both of these changes seem to have helped out a lot. It's bearable now, it's about a 5 second delay when it happens.

I'm thinking that the issue is with a ton of JavaScript (20k+ lines.) I'm just working with JavaScript, so it's hard for me to rule that out right now.

Thanks,
Eric

Running IntelliJ with Java 1.6 seems to make it even more responsive might want to try it out with 1.6.
