Not exactly a very technical explanation, but here's an insider's
take:

...on Friday we launched a platform rearchitecture based on
loose-coupling, web standards, and a move from JSP (via
Tomcat) to PHP. The website doesn't look much different, but
hopefully we can now stop being a byword for unacceptably
poky site performance.

who, by the way, was fired for writing it:

MySQL JDBC driver...
