In discussions about "NoSQL" systems, I've found out that some of the developers complaining about RDBMS performance didn't even know what indexes were.
Usually they learned how to use MySQL from thirdhand PHP & MySQL tutorials off somebody's blog or something, and thought it was representative of all RDBMSs.
Not saying everyone using "NoSQL" is poorly informed, just that sometimes peoples' impressions of performance aren't very accurate. It makes me suspicious when somebody's benchmark only uses MySQL.
