Tip: Close other heavy tabs/apps and disable “battery saver” for more consistent results.
Browsers run in a security sandbox, so they cannot read/write your disk directly.

After the test, the database is cleared to free space.
Note: Private browsing, storage quotas, low disk space, or extensions can significantly lower results.
