Re: [PERFORM] Simple join doesn't use index

Guys, thanks a lot for your input. It is very valuable for us. We plan to
fix a separate dev server similar to production one, copy all data there
and try you suggestions as we really don't want to do it on production
server. I also noticed that IOPS jumps to 100% when running this query. So
it is a bit scary to make those changes in production directly. Will report
back on the progress and findings.
