Native languages for web development

Why are "native" languages* almost never used for web development? Shouldn't FastCGI be just as good as what web servers do with Perl or PHP? What am I missing?

* languages designed for AOT compilation to opcodes like C++, Ada, C, D, Pascal, or Go

Perl is better than Ruby, PHP, Python and Go in terms of sheer productivity. http://news.ycombinator.com/item?id=4379142
