how far can we go using vstart.sh script for fake dev cluster-HELP

Hi, Ceph source code contains a script called vstart.sh which allows developers to quickly test their code using a simple deployment on your development system. Here: https://docs.ceph.com/en/latest//dev/quick_guide/ I am really curious that how far we can go with vstart.sh script. While my development cluster is running, I use tools like rados bench, rbd and rbd-nbd to benchmark simple workload and test my code. Do we have options to change the network settings in the fake cluster built from vstart script and later benchmark it? For example , trying 1gbit ethernet and 10gbit ethernet. Thanks
