well, I don't doubt you did experience it, but it sounds quite unlikely
(or like a bug). To be a bit picky: How did you measure that factor?
But you're right: In fact, some applications will probably work better
in "trusted" mode (see "ForwardX11" in ssh_config(5)). However, usually
applications are not supposed to behave in a way where -Y (i.e.
trusting all and everything) has improvements...

More to the OP: In any way, be sure to learn about the security
problems that are related to forwarding X connections.
