C++ is rarely used on the Amiga and it's slower.
That's highly debatable. If you simply compile C sources with a C++ compiler there's no difference unless you're using a retarded compiler. C++ function objects can be inlined, while function pointers in C can not. Some sorting algorithms have proven to be many times faster on C++ due to this.
It is true that certain parts of the C++ language are slow, like using virtual functions in a tight loop. It's really a matter of knowing your language, knowing the little 'gotchas'.
In my experience, the main disadvantage with C++ is slower compiling, especially when using templates. But I'm a little tired of reading "use C instead" every time someone mentions C++ on the Amiga.
