# Why does Storage Studio's background work slow down when I start using my Mac?

On purpose — your own work always comes first. Storage Studio keeps reading how recently you used the keyboard and trackpad, and while you're actively working it shrinks its background budget to a small fraction so you don't feel it.

Once you've stepped away for a little while, it lets itself catch up quietly, and it allows itself a bit more when your Mac is plugged in than when it's on battery. The result is that things like building your storage profile or measuring folder sizes may finish a few minutes later than they could — Storage Studio has no deadline, and it would rather be late than in your way.

Anything you start yourself, such as **Scan now** in the Duplicates window, isn't treated as background work.
