plugin loading time

I had to disable Falcon caching (as you no longer support it) and to buy/install WP Rocket. Then I decided to re-check plugins impact on page loading time (I use P3 profiler every time I change plugins). I was really shocked to see 5x increase in Wordfence plugin loading time between Jan and Oct 2016. Does it have anything to do with disabled Falcon caching? Or this is the result of added functionality between the versions? My site is running on VPS and there were no major changes between Jan and Oct, at least in terms of hardware.

See attached screenshots with P3 results for Jan and Oct here:
