Seeing latency for http calls via external and internal application loadbalancers

[srinivasa458]

HI Colleagues, we are seeing high latency in the application calls from internet through external application loadbalancer through internal application loadbalancer to VMs.

All the VM metrics are under control. But we see latency reaching till 7 sec when we increased volume of connnections.
Does GCP ALbs choke during load testing conditions?

backend latency is also in control from both LBs to their respective backends. But still we see latency during medium volume conditions.
