Perfomance of Queue getting large
Hi, 

really love the project! We are using a RateLimiterQueue in memory on a node js server. So users can make 10 requests per second and anything above is queued and processed later. That all works fine. We are just unsure what value to set the max queue size to. 

Do you have any idea or benchmark of the performance of the queue size when it grows?

So e.g. what happens if thousands of requests are stored in the queue?
