How to increase Router performance of processing registration message.

[Zhongying Tu]

Hi, guys:

     I found that the Router component seems that only can process about 60 registration messages of instances per sweep period (30secs), if exceeded 60, Router would came across the "Slow consumer detected" exception. 

     However, if we increase the router-cluster scale, the performance seems to be even worse, due to each router need to process more registration messages. 

    Does anyone has good ideas for this issue?

    Thx~

Increasing the “max_pending” configuration of NATS works, and seems pretty easy, it simply increase the standard of “slow consumers”.
