>very high-performance C++
C++ does not automatically mean "very high-performance". A lot of users get worse framerates than with Minecraft (not everyone, though!), and the entity/"mob" code used to be insanely slow, at least a year ago.

(GP stated that this software is high-performance, and that it is written in C++. They didn't claim it to be high-performance because of C++.)
Lots of those problems have since been fixed though. I believe a rewrite in C++ today would bring more problem than it solves (which, BTW, Mojang is kind-of doing with Minecraft PE).
