@yoholiao Hello!

Is this issue a question or a bug? Let's consider that first... Do you use IIS to host downstream services or Ocelot app?

without rules

Considering your complex Ocelot setup: Consul service discovery, Load Balancer, Delegating handlers (two types), Kubernetes hosting... I would say your solution and setup is quite complex. Your delegating handlers can do additional tasks which affect total processing time of the request... I would say the root cause can be inside of your delegating handlers.

Sorry we cannot accept the issue because it is related to your environment.
