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:

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
