Hi Jie,
I know I said I was going to get testing on this months ago but I've
been juggling between 3 systems due to disk failures and other hardware
configuration issues. Anyways, I've take a baseline run of only the
power test using a 1GB database with the patch 09-17 patch against a
snapshot of pgsql from 2006-09-17:
http://dbt.osdl.org/dbt/dbt3testing/results/dev8-007/2/
Do you think the 1GB scale factor will be sufficient for testing as it
will certainly be faster? Do you think testing with just a power test
will be sufficient for now? I really don't have a good reason why I
didn't run a throughput test other than to save time. :) I also wanted
to get your opinion again on which indexes we will want to try first.
Thanks,
Mark
