The phrase "C++ is an extremely fast language -- meaning software built with it runs at high speed" needs to be changed to "It's possible to build high speed software with C++".
I take any performance claims made by a particular language with a pretty big grain of salt (particularly those made vs Java/JVM) unless they're accompanied by some reasonably sophisticated benchmarks and source that actually show a performance difference -- not just one that low-level language enthusiasts presume exists.
