# Will a big transfer slow down my Mac or my internet connection?

Storage Studio is built to stay out of your way, but a big upload can still use a lot of your connection. To keep things smooth:

- Set a **Bandwidth limit** so the transfer leaves room for calls and browsing.
- Lower **Parallel transfers** on a slow connection.
- Schedule big recurring jobs for the night.

When your Mac is under heavy load, Storage Studio holds back scheduled transfers and starts them once things settle, so your own work comes first.
