I'm currently playing with dbt2 and am wondering, if the results I'm
getting are reasonable. I'm testing a 2x Dual Core Xeon system with 4 GB
of RAM and 8 SATA HDDs attached via Areca RAID Controller w/ battery
backed write cache. Seven of the eight platters are configured as one
RAID6, one spare drive. That should leave five platters for distributing
read only accesses.
The NOTPM numbers I'm getting are suspiciously low, IMO, but maybe I'm
expecting too much. What do you think, is this reasonable or do I have
to twiddle with the configuration somewhat more?
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.
