Neutron bottleneck


It was mentioned that L3 external traffic egress to internet through Neutron, also it was mentioned that theoritaclly OS scales up without limit, My question if we have bigger number of compute nodes and consequently VM's then We need to scale up Neutron as well, please correct me if I am wrong.

If I am right then isn't this adding latency which impact perfromance, is there any work to optimize such issue specially with using namespaces?

    Hello Mohab,

    Yes, the more VMs that use L3 traffic the more overall traffic would go through your Neutron systems. You would add more Neutron nodes to handle the traffic. How many and when to add would depend on the overall amount of traffic and the resources of each Neutron server.
