tldr: mysql is getting worse for small, in memory workloads with low concurrency. for the average medium to high traffic mysql install, i find 5.7 to be much faster than 5.6 or mariadb where concurrency and varying workloads prevail. ymmv, do your own testing to see which db is a good platform for your specific workload. maybe it's mysql 5.6 maybe it's mariadb, maybe it's postgres. for me mysql 5.7 brings much awaited niceness, saner defaults and even though not all workloads are better on it i think oracle is really trying to iterate. likely they will fix this regression and there would be little reason to use it over 5.6 or older.
