These two attributes seem to do similar things. Infact, do they do the same thing? Or is it that in the case of ref a reference is passed, and in the case of inout a value is copies in via the stack and then passed back out?

Why would one use inout instead of ref since inout must be slower for larger objects.

They are exactly the same.  There is no semantic difference, only what word is used.

'ref' was introduced in anticipation of reference return values or possibly even general reference types.  Having an 'inout' return value or an 'inout' integer doesn't make much sense other than with parameters, but 'ref' does.
