Hi Fengnan, We had been testing cost based faire call queue internally. We also saw latency increase, and we are trying to debug into this issue as well. Current suspicion is that the way that the metrics were generated might be introducing too much overhead. We are in the process of trying to reproduce this using Dynamometer. If this is something you would be interested in, we can follow up on working together on this issue.
