'Easily obtained' I don't consider an improvement obtained switching from/avoiding a high level language that allows me useful abstractions and to avoid bookkeeping, to C++, an easy thing. Yes, if the thing is just -slow-, optimize it. But never start out "We can't have this thing be slow; let's write it in C++!" unless you already have some metrics showing that it's -too- slow in a safer language.
