speed test education

I do not have a speed problem but I am just looking for reasons why speed tests give different readings.
I have 900Mbs to the router but using other speed tests can get anything fron 300 Mbs to 900Mbs depending on the tester. Sometimes if I change server on the test site the speed sometimes rises.

It depends on more than just your link. If your link can do 900,but somewhere along the route between the speedtest server and you, speeds are limited to 300, then 300 is all you will see.

Are you seeing differences on *our tester* between times, or various testers?

Computer networks are complicated and different routes can have different speeds. It's much like a road network - the time to get to the centre of London 60 miles away can be different to the time it takes to get the centre of Birmingham 60 miles away.

And unless you frequently access data stored in the same location as the speed test server the throughput might have little bearing on what you experience in normal use.

The value of speed tests is in sticking to one long term so that you can see any unusual results and even better use multiple test servers so that you can tell if a slowdown is local to you (affects all speed tests) or specific to one particular route (only affects a couple of speed tests).

And if you're testing using a wireless connection take all results with a pinch of salt.
