The limits on Task Queue calls can be found on the Quota page <https://cloud.google.com/appengine/quotas#Task_Queue>, specifically the 'Queue execution rate' being of importance.
Too many tasks being executed on a single queue will inevitably result in underlying contention. This leads to the slow down of task execution (aka exponential-backoff retry) while tasks wait for resources to handle them. It is recommended to instead shard your tasks across multiple queues to get around this limit. You can also tweak your queue.yaml <https://cloud.google.com/appengine/docs/standard/python/config/queueref> *'max_concurrent_requests'* setting to prevent any single queue from hitting this limit. Additionally, it is always good to check your logs to ensure that you didn't see any errors during the gap, as you could be hitting other quotas limits (which would require time to refill). -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
