[neutron] When num of port mappings is substantial, the response time of List API so slow
Hello，
I have a Victoria cluster with 1 controller node(also have nova-compute service) and two compute node. ALL node boasts 128 CPU cores and 512GB of memory.
I established 1500 port mappings for a single floating IP A. At this point, the response time for the "List Floating IP Port Forwardings" API[1] becomes remarkably slow, approaching a duration of 9 minutes.
Does anyone comprehend the cause of this phenomenon or how should I investigate it?
I am immensely grateful for any assistance provided.
Best regards, Han Guangyu
