Then, we ran a postgresql benchmark - pgbench - that submits a few transactions against a small database. Simulating 15 clients running 200 transactions each we obtained this result, in transaction per second:

tps: 1462.109434 (excluding connections establishing)

where a non-virtualized workstation result is something like:

tps: 5.833331 (excluding connections establishing)

Of course what i meant was:

5.8 tps virtualized, 1462 tps non-virtualized.
