Did this change occur recently? I've noticed in the past 3-4 months Instagram has become a lot slower. To be fair, it's started to gain some speed in the past month, but I'd be interested to see how this increase in latency coincided with the migration to React Native.

When teams at Facebook roll out features or rewrites like this, they almost always monitor performance metrics so I'm comfortable claiming that React Native is unlikely to be responsible for slowness you've seen recently.
