Sorry, I couldn't help it.
Running at 1.2 GHz these things are obviously not very fast in a straight line (says the guy whose main DB is still running on a 900MHz Sparc III), but for certain types of database and web/apps server I'm guessing they are probably quite good.
I will have to recommend them to my firms IT architect - the same Guy who has insisted on J2EE as it is obvious that our system needs to be massively scalable - although I am still wondering if this means going from 2 to 4 users, or perhaps even 8 !
