Pretty much what the title says. In our large project the compiler seems to spend something like 10-20% of its time checking the attributes on methods, in particular whether the method is a direct call or not (a runner up is availability checks). Given that direct calls are supposed to be a carefully used feature sprinkled on just a few performance-sensitive parts of a codebase, the cost to check whether a method is using direct calls seems fairly high.
