MARK> So it looks like the regression at --num_threads==1 is real. <cut> Hakan, when you run tests, please make a test between MariaDB 5.1 and MariaDB 5.2 and check if there is any performance differences when 5.2 is run without userstats enabled (default). The only thing that I can think of that could cause any regression is that wrapper around ha_read calls. As these are small online functions I can't see how the overhead could be notable.
