I've used AIX since it ran on the RT. I've used CVS since a buddy said "hey...this guy has some shell scripts that work better than SCCS" (i.e. the late 80s). I've done OS performance analysis for decades. I'm quite clear on how those boxes perform. Quit doubling down on the bullshit that an unloaded 660 with server class I/O is outperformed by a mobile P3 cramming data down a laptop IDE bus. It never happened. What happened is something like what mattzito described and you just have no idea how real systems are deployed and managed.
