It can sometimes feel like IntelliJ IDEA uses a lot more of your computer's resources than other IDEs. Usually, it's when you get started with a new project and IntelliJ IDEA has to index the code and its dependencies. The IDE should speed up once the indexes are generated, they're there to make the IDE work faster after all, also nowadays there's an option to download the commonly used indexes which should also be a bit faster.
However, I have also found that using IntelliJ IDEA with an SSD is significantly better performance than a spinning rust drive, I guess most laptops use SSDs now but I'm not sure if enterprise hardware has caught up.
