You may have noticed timelines are a bit faster, here is how we did it:

Every home timeline request previously used 4 sql queries (following, private profiles, user level mute/block profiles and the timeline query itself).

We cached following and private profiles, reduced pagination limit from 5 to 3 and re-enabled infinite scroll.

There is still a lot of room for performance optimization including caching mute/blocked profile lists and redis timeline based cursor pagination which we plan to finish in the next week! #pixeldev
