title: API Gateway/NLB/ECS Latency
body: <p>I have a number of services deployed in ECS. They register with a Network Load Balancer (via a target group). The NLB is private, and is accessed via API Gateway + a VPC link.</p>
  
  <p>Most of the time, requests to my services take ~4-5 seconds, but occasionally &lt; 100ms. The latter should be the standard; the actual requests are served by my node instances in ~10ms or less. I'm starting to dig into this, but was wondering if there was a common bottleneck in setups similar to what I'm currently using.</p>
  
  <p>Any insight would be greatly appreciated!</p>
