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.
You've enabled the validation options in the configuration. It does warn they are slow and recommend not to enable them, but on some servers they are extremely slow. We'll try and optimise them and/or hide them.
Go to http://yoursite/?keep_novalidate=1 and navigate back to the configuration (Admin Zone > Setup > Configuration > Site options) and disable the validation options.
