What's wrong with ms edge

Forgive the obvious question.. how does that compare with using a different browser?

Hi, you don't have to remove Edge.

You can simply download and install an additional browser e.g. Google Chrome, just like any other program.
No need to change the defaults for anything - just use it to browse to the same page and compare.

Do you have any other devices (other PC, smart TV, smrt phone) that you can use to compare, that are connected to the same router?

Diagnosing a problem requires some actions- attempts to try to find out what is happening. There are many many reasons whay pages may load slowly- e.g.

- very slow and limited connection
- servers busy
- poor DNS performance (the server that interprets URL's)
- high resource usage on your PC
- competition for bandwidth on your own router
etc etc
