The performance tests here seem about useless. When memcache is slower than all your databases its a good indicator that after your first call all the databases just cached the request, to get meaningful performance metrics you would need to use sizable databases and more realistic use cases. It's not enough to just publisher a disclaimer, why not just do it right in the first place? It also states transactions as a benefit of MYSQL then shows the performance tests against the MyISAM engine which doesn't support transactions. This also explains why the MyuSQL inserts might be faster than any others.
