[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
