Peter and me spent quite some time working on this project while being employed by MySQL and it is great to see results finally publicly available.
The story began about year ago when C’T magazine had called for Database competiton using Dell DVD Store benchmark (details available here: http://firebird.sourceforge.net/connect/ct-dbContest.html).
Most interesting results are (more orders per minute are better ):
MySQL5/PHP (our solution) : 3664 orders per minute
DB2/Java : 1537 opm
Oracle / Java: 1412 opm
PostgreSQL / PHP: 120 opm
MySQL5/PHP on two boxes: 6000 opm.
I wonder how C’T have got such low results because on the same hardware I got ~7000 opm on one box and
~12000 opm on two boxes, but that does not matter.
