My computer slows down a lot when I try to edit a page

When I try to edit a page, it slows to a crawl, especially when I delete stuff. This is particularly worrying because my desktop is a beast, and I didn't have this kind of problem on my old, graphics card-failing computer. Does anyone else have this problem?

I use Windows 10.

possible duplicate thread you should read.

After reading that, as several people have reported this problem, I suggest filing a bugreport at Query Bugs. For performance type problems, you should always list your operating system and the browser you use.
