The tick size is 1ms and the wheel size is 20. The timeout was set to 200ms. The data size of a request was 100 bytes. For a low timeout rate case, we chose 75percentile = 60ms and 50percentile = 20. And for a high timeout rate case, we chose 75percentile = 400ms and 50percentile = 200ms. Total 1 million requests are enqueued in each run.

Requests are actively completed by a separate thread. Requests that are supposed to be completed before timeout are enqueued to another DelayQueue. And a separate thread keeps polling and completes them. There is no guarantee of accuracy in terms of actual completion time.
