I finally got round to running sysprof on my system. I did 6 tests, 3 with
blur, 3 without, under the same stress conditions(5 open windows, a bit of
moving them about, resizing, etc). I'll only attach two files here, because
the others are almost identical.  The conclusion of the tests?

Kwin stays at about 34% under normal load, without the blur plugin. With it
enabled, it skyrockets to 55%(a good 70% more than without blur.) I'll also
attach some screenshots of the test results, in order for you to be able to
catch an easier glimpse of them.
