The scaling factor should be much greater than the number of clients. Otherwise, multiple clients would conflict on
thesame row of branches table, which might hide the additional overhead of the global metacache.
And I think -j should be 12 or so on your 16-core server, so that the pgbench client can maximize its concurrency.
