Jean-Paul asked to also compare with NEO/py cluster where there are 4 storage nodes. I've made corresponding changes to neotest and zwrk

and the results for ASUS machine (8 CPU) and Z600 machine (24 CPU) are below.

( rendered properly here )

( neo/go/sqlite is omitted because it does not yet support partitioned data and for "·P4" case (partitioned by 4) the datasets are generated partitioned into 4 databases ).
