That's weird, then - with proper hashing, the total number of filter rules
should not affect CPU load too much, since only very few of the filters
actually have to be traversed. Maybe it's caused by something else, or the
hashing does not work as expected.

Good question. Actually I can't answer it properly. For my filters, the
order either did not really matter or I had few enough of them to use
the priority parameter to order them properly.
