Reining in the thundering herd: Getting to 80% CPU utilization with Django
Tangent, but I always had a different understanding of the “thundering herd” problem; that is, if a service is down for whatever reason, and it’s brought back online, it immediately grinds to a halt again because there are a bazillion requests waiting to be handled.<p>And the solution to this problem is to slowly, rate-limited, bring the service back online, rather than letting the whole thundering herd go through the door immediately.
