A webpage with videos, animations, and transitions, especially if you have it opened on multiple devices can seriously hamper performance even on the beefiest dev machines. Here are some steps you can take to improve performance.
Animations are often the biggest resource hog when you have multiple devices in your workspace. Thankfully, you can disable them (and many more potential performance hogs).
Click on the Performance icon on the left side of the Workspace Toolbar to open the dropdown.

The Full Mode and Resizable Mode buttons are located on the right side of the Workspace Toolbar.
To focus on a single device, use the Focus Mode by clicking the 3 dot menu and selecting Focus.
You can save presets with different device configurations, and switch to one with several devices only when you want to check if everything looks fine on every device.
