kubernetes – Aspnet core identity load test bad performance

I’m running load tests on the API for user login. The project is basically the defaul template with aspnet core identity. So I wasn’t expecting these bad performances:

  • 1 Pod on kubernetes(GCP)
  • PostgreeSQL on GCP (vCPU: 4 | Ram: 15 GB | Hard Disk SSD:15 GB)
  • AspentUser count: 3.387.988

The load test result:
enter image description here

Looking at the postgree log the query response time is below 100 ms.

Is anyone experiencing the same performance issues on kubernetes?

Thanks in advance
