Not necessarily. I've moved C++ code to C#, and it got much faster. The reason is because of copy (and other flavors of) c'tors that needlessly copied data because it was either happening unbeknownst to the author, or it was easier than dealing with the consequences of proper aliasing semantics. I have a feeling that this is not uncommon. So IOW, bad manual memory management is going to perform worse than modern GC systems. Pretty much the same as an automatic transmission on a high-end sports sedan -- unless you really know what you're doing, the AT is going to do a better job of shifting than you are.
