When you are installing new apps or adding content to your LINK BAR, the system may be a bit slower when dealing with multiple things.
Here is a couple of things you should know.

1. You need a speedy internet connection to download all the content you added.
2. Wait for everything to be finished, then you can enjoy the system without any issues.
3. Reboot LINK BAR after installing all apps. A fresh reboot can help and enhance performance.
