Btw, it is hard to give to those tests much value without more details about:
- The hardware used. How many CPUs? How much memory?
- The settings of server, like postgresql.conf. How many shared
buffers? Was catalog and/or pgbench data cached? pre-warmed perhaps?
- Structure of the cluster (1Co/1Da per server, all at the same place?)
