There is a slow down in the time it takes to load recentchanges reported by users in hewiki following the new edit filters.

This should be evaluated (if not already done) - though I couldn't find a specific board for it in graphana.
Here is my personal crappy evaluation as anonymous user (to avoid loading specific user scripts)
* Firefox 55: contentLoaded 1.43s-1.61s, load: 6.7s-7.6s (3 tries)
* Chromium 60.0.3112: content loaded: 215ms-748ms, load: 462ms-1.23s (3 tries)
Sometimes it can even get as high as 18s to load in FF.
Compared to some random wiki page (not RC):
* Firefox: contentLoaded 820-850ms, load: 2.40-2.60s (3 tries)
* Chromium: content loaded: 150-362ms load: 335-384ms
__Suggestion:__
Don't use jquery.ready when DOMContentLoaded is sufficient. (see example for this magic in ULS: https://gerrit.wikimedia.org/r/#/c/299285/ ).
Specifically I would recommend to check carefully this line in mw.rcfilters.init.js:
```
$( rcfilters.init );
```
