Re: Why does MySQL's performance decrease when queries are executed in parallel?

Rick, thanks a lot for the explanation. I'm already using the XtraDB engine so the issue is not related to InnoDB. For the moment I tend to think that this sort of unscalable behaviour is due to a bottleneck of some kind that happens during quereing MySQL. The most probable reason is heavy memory usage which about 7000 hits for a single query totalling into 700,000 hits a second (as was suggested on StackOverflow, here's the related link: http://stackoverflow.com/a/11341343/1200148)
