We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.

Beyond AMPHP, there is also ReactPHP, Swoole and Hyperf. AMPHP seems most relevant though.
Another complexity is right now to use AMPHP we'd have to plug in its modules to replace core querying and HTTP functionality in relevant cases, which would complicate things, be a lot of work, and potentially hurt performance in different ways.
