The UltraSPARC T2 and file security
If you were to test the performance of an UltraSPARC T2 against that of the traditional dual Xeon by running a single "gzip" or "tar" on a large, NFS mounted, storage pool using server side encyrpted file storage, the 1.4Ghz T2 would easily blow away the dual Xeon - because it has hardware integrated cryptology and networking, and the Xeon doesn't.
