Following a number of talks at Drupalcamp London which mentioned MariaDB, we've been looking into using it ourselves in place of MySQL.
Pretty much unequivocally, what I was hearing from Drupalers was that it was a definite improvement. With that in mind, my colleague Dave managed to get it working along with nginx on our shared VM environment.
However, before we committed to it, he wanted the evidence he found was pretty equivocal, and if anything it suggested that MariaDB performed worse than MySQL 5.6 under most conditions! You have to go to the - still alpha - v10 of MariaDB before you find even similar performance.
This is all very confusing. Anyone had any experience with either? Could they point to any benchmarks, or - better still - explain the ones we managed to come across?

Hi JP. No experience here
Hi JP.
No experience here yet, although our latest member of the team (Maria) is keen for us to try it soon.
Would be very interested to see some real world benchmarks on a reasonably sized Drupal site. I'll let you know if we find the time to do that.
In the mean time, let us know what else you find.
All the best.
Finn.
It's weird
That we see everyone raving about MariaDB - and want to give it a go myself, don't get me wrong! - but the metrics all suggest the opposite. Anyway, I'll let you know if we get any hard benchmarks of our own.
