Dear Authors,

I'd been using Eclipse for well over 15 years, and recently switched to IntelliJ.

What is your take on IntelliJ being "Resouce intensive" requiring significant RAM and CPU power, at least that is
I was told when I was switching from Eclipse.

Thanks
Sundar

I had a similar experience a few years back when I was considering moving to IntelliJ.  My workstation at the time didn't seem to have enough oomph and the IDE felt very sluggish.  I have since upgraded desktop and I'm guessing it would be fine now, but it does seems like IntelliJ needs a significant amount of CPU and RAM resources.

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.

That makes sense, thanks for that answer.
