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.
This issue needs separating out... some of the issues you already linked to, so any expansion or discussion should be solely under those issues. Other things which standalone should be in their own issues, e.g. filedump permissions wouldn't be dependent on, or have a dependency from, the other parts of this.
Individual issues can then be thought about more easily, and individually sponsored.
