These are benchmark results of an implementation of async.queue based on maintaining an index into the queue as items are processed instead of shifting items off the queue. The new implementation is shown as "indexed async.queue" in the benchmark results, with the old one shown as "upstream async.queue". For larger queues, the performance differ…
