It isn't bad manners to ask Rusky or pcwalton to show measurements in support of their claims.
It isn't bad manners to trust that when steveklabnik answers "No, as optimizing performance hasn't been a focus, shipping good language semantics has been." that's what he means.
Optimizing the workloads tested on the benchmarks game has not been a focus.
