I've attached a profile, the relevant part is content process #3 beginning about 7s into the profile.
Also, the Activity Stream version is: 2017.09.12.1376-781e5de5
Hm, I wonder if the extra data URIs for highlights is what's causing this. We could take a look at profiling that specifically, maybe turn on the dev version of react locally if that doesn't turn anything up

After some investigation it looks like the Sections component's render function is being called 9 times on every load (since it is receiving 9 SECTION_UPDATE_CARD events), that's something we might want to look more into
Hopefully fixed by https://github.com/mozilla/activity-stream/pull/3480 to be uplifted via bug 1399970.

I just re-enabled activity stream, I'll let you know if I see the same thing again.
I'm curious though, the lag this created for me made the browser nearly unusable, but it doesn't seem like this was reported by anybody else?  Could there be something specific about my profile that made this especially noticeable for me?
