The main purpose of Sloth is to discard tabs at startup. This is useful for performance and memory usage reasons. Besides, it also reduces the initial loading time of the browser and improves the performance of the browser in the following ways:

The memory footprint is reduced, especially if the browser is open for a long time.

This reduction in memory usage allows more tabs to be stored in the memory, which is beneficial for long-term performance.

This is the main benefit for users with low-end devices, who can take full advantage of these features.

To activate Sloth, go to settings and enable the "Discard Tabs at Startup" option.
