I think you completely missed the point of my email; what my mail
was saying was:

 - It's interesting that such large speed differences exist
   in the testing.

 - I'm a little skeptical that the compiler had much to do with it.

 - Gentoo would be a great platform for verifying that one way or 
   the other, so it would be great if those tests were extended
   to do an apples-versus-apples comparison with only compiler
   flags changed.
