These 404 scripts are key.

Nah, that's fine.

This is a configuration problem, and is causing your slowdown.
What is happening is that you have a path set wrong somewhere, and the
browser is using that to fetch things like CSS and images. However,
whenever it 404s, it launches a Perl script, and you have several 404s
happening at once. If it could just deliver the file, it'd be very fast
and take next to no resources, but as you have several incorrect
requests going out, each one launches a script, you end up with many
running at once, and things go slow.
Fix your CSS and image paths, etc. and your koha will be fast again.
You can get more information by using the browser's inspection thing to
view network traffic and see which ones are returning 404. Ideally it
should be none.
