There's clearly something wrong. The response times are ridiculously
high, they should be < 5 seconds (except for stock level transaction) to
pass a TPC-C test. I wonder if you built any indexes at all?

The configuration I'm running here has 3 data drives, and I'm getting
reasonable results with ~100 warehouses, at ~1200 noTPM.
