Latency when scrolling deep in feed
Summary
When you get deep in a feed, things can take longer than should be necessary to load.
Steps to reproduce
Go deep into your newsfeed, observe CPU increases and increased processing times.
Platform information
Replicated slightly on Chrome - could see the memory increase but 16GB seemed to deal with it pretty well - presumably on a machine with less RAM this would be more problematic.
Firefox shows heavy CPU consumption and performance issues.
What is the current bug behavior?
High latency
What is the expected correct behavior?
Acceptable latency
Relevant logs and/or screenshots
(Paste any relevant logs - please use code blocks (```) to format console output, logs, and code as it's very hard to read otherwise.)
Possible fixes
(If you can, link to the line of code that might be responsible for the problem)
