I have small project here of less than 100 kLOC of source code. Yet Intellij idea is lagging when I click on main menu or change file. When I raised the memory from 8 gigabytes to 12 gigabytes, the situation seems to be acceptable again. I still can give much more RAM to idea, sure, but I think I should not need that much.

What could be the process to prevent this and make editor responsible? I don’t have enabled more than 5 plugins and most of default ones are disabled. Caches are regularly fully cleaned, because idea keeps corrupting them.
