> Our deployment environments have a lot of churn, with many short-live frameworks that often revive offers. Running the allocator takes a long time (from seconds up to minutes).
> In this situation, event-triggered allocation causes the event queue in the allocator process to get very long, and the allocator effectively becomes unresponsive (eg. a revive offers message takes too long to come to the head of the queue).
> We have been running a patch to remove all the event-triggered allocations and only allocate periodically on the allocation interval. This works great and really improves responsiveness.
