Best Linux for running Windows?

[BigglesPiP]

Well, you did say Solaris is often faster than Linux at pure computational tasks without offering any evidence. I'd be interested in any links that you may have, so I and others, can better evaluate Solaris/ open Solaris.

Many thanks!

Maybe he's thinking of SPARC architecture?

Which may be able to execute code compiled for older or more limited instruction sets more quickly.
