Do you actually think that because Linux "flies" on an eight-core Opteron system, scalability is being touted here? This is utter nonsense, as Solaris has supported that number of CPUs for years (at least greater than or equal to 64 and up to 16 EBytes of memory on UltraSPARC-III or higher and AMD64).
The reason for this is Solaris has far more advanced kernel-level synchronization primitives than (look at how many race-condition-related security vulnerabilities the Linux kernel has) than Linux to make this scalability possible. It stands to reason that (a) if Linux does have sufficient synchronization mechanisms (b) they aren't being used or (c) they aren't sufficient.
So Linux may "fly" on your eight-core Opterons, but the fan is only a couple of feet away at any given moment.
