Re: pgbench: Support Multiple Simultaneous Runs (with Mean and Std. Dev.)

Tom,

I noticed in this thread:

http://archives.postgresql.org/pgsql-performance/2005-12/msg00206.php

you state:

"Try something like "-s 10 -c 10 -t 3000" to get numbers reflecting test
conditions more like what the TPC council had in mind when they designed
this benchmark.  I tend to repeat such a test 3 times to see if the
numbers are repeatable, and quote the middle TPS number as long as
they're not too far apart."

The -x I added is to make your "3 times" easier. Sure, it's just
sugar, but if this is part of the recommended use of the tool, or
even a personal case study from the core team, I figured it might be
of use to others. Anyway, just a followup since I was going through
the archives and found a mild argument in favor it from you. :)
