Re: Power 6 vs Power 8

Very cool results, Rob - this confirms the charts IBM has on P8 performance - even though processor speed is about the same, the design is so much faster.

Nice to see, so that even single-threaded, RPGish stuff will benefit - unlike the deal some years ago.

This was a Domino lpar.
Once a week it runs Domino tasks: COMPACT, FIXUP, UPDALL at low business
periods.

Power 6:
04/17/2014 05:00:00 Running Program document for 'FIXUP -L -j'
04/17/2014 05:00:12 Database Fixup: Started: -L -j
04/17/2014 06:23:13 Database Fixup: Shutdown
04/23/2014 03:10:23 Running Program document for 'COMPACT -B'
04/23/2014 07:50:51 Database compactor process shutdown
04/23/2014 04:00:40 Running Program document for 'UPDALL -r'
04/23/2014 04:00:43 Index update process started: -r
04/23/2014 07:12:28 Index update process shutdown

Power 8
04/30/2014 03:10:02 Running Program document for 'COMPACT -B'
04/30/2014 04:50:29 Database compactor process shutdown
Runtime went from 4:40 to 1:40
04/30/2014 04:00:19 Running Program document for 'UPDALL -r'
04/30/2014 04:00:20 Index update process started: -r
04/30/2014 05:09:27 Index update process shutdown
Runtime went from 3:12 to 1:09
05/01/2014 05:00:46 Running Program document for 'FIXUP -L -j'
05/01/2014 05:00:49 Database Fixup: Started: -L -j
05/01/2014 05:18:04 Database Fixup: Shutdown
Runtime went from 1:23 to 0:18.

Same lpar.
Same Domino partition

Went from being a 'host' partition on Power 6 down to being a 'guest'
partition on Power 8.
