In my previous article, Comparisons of Proxies for MySQL, I showed how MySQL Router was the lesser performing Proxy in the comparison. From that time to now, we had several MySQL releases and, of course, also some new MySQL Router ones.

Most importantly, we also had MySQL Router going back to being a level 7 proxy capable of redirecting traffic in case of R/W operations (see this).

All these bring me hope that we will also have some good improvements in what is a basic functionality in a router: routing.
