As mentioned last week, one of the important cleanup tasks that is not yet in progress is updating the [gabbit](https://opendev.org/openstack/placement/src/branch/master/gate/gabbits/neste...)
that creates the nested topology that's used in nested performance testing. The topology there is simple, unrealistic, and doesn't sufficiently exercise the several features that may be used during a query that desires a nested response. This needs to be someone who is more closely related to real world use of nested than me. efried? gibi?
With regards to the topology for nested performance testing, I think a more-complicated but reasonably typical nested topology would be a compute node with something like 2/4 numa nodes, with a mix of memory page sizes (4K/2MB/1GB), with HyperThreading, and with a few NUMA-aware PCI devices (SRIOV, FPGA, vGPU, etc.).
