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 should probably be run as separate from cron_bridge.php if at all possible, unless you force this to be the very first thing that runs each time cron_bridge.php runs. Reason for this is because if it's not the first thing that runs, and something in the cron tasks queue fails before it gets to this, then health check might not run.
