Public bug reported:

When creating large numbers of networks with dhcp enabled at the same
time, dhcp agent will periodically collect network information via rpc
calls from Neutron server, which is a time consuming job. In our test
environment, creating 4096 networks at the same time will lead to more
than 90% usage of the cpus.
