I set all my LAN traffic to route through the connection, as per the guide:
/ip firewall address-list
add address=192.168.100.0/24 list=local
For the most part everything seems to be working, however I have noticed that my Instagram app doesn’t refresh and same with my Gmail. Also can’t seem to get Chromecast to work, when casting Youtube or other content. Not sure if there is something i may have missed?
That test suggested by @msatter is intended to compare the results with and without the policy with action=none as described there. So the absolute value (2 seconds) is not important as such, what is important is whether adding the policy makes it shorter or not.
