Speed tests are a useful way to know how good of an upload you have for self-hosting.
Your ISP (Internet Service Provider) is aware of these tests and will likely prioritize traffic for the most popular tests. This could mean receiving overly generous speed estimates.
You’ll want to run (and compare) Speed Tests that are not just the first search result. We’ll be using Libre Speed Test as it is a decentralized, fully open source solution. Click here for the source code.

Hopefully this proves helpful in deciding whether self hosting is right for you! Good luck.
