Those are some awfully specific numbers for a very vague operation. So,
since that's true, do you imply that -every- Cadence operation takes 10
minutes on a 2.2GHz Pentium or that only those which take 10 minutes
take 29 minutes on a V880, regardless of how they may benefit from each
system's different characteristics? That, of course, also says nothing
about the memory load involved, storage I/O, number of iterations
performed, or any other number of variables.
According to my ACTUAL USERS, they're more productive on their Suns.

So, because a particular PC will run a particular operation in Cadence
in nearly 1/3 the time that a particular Sun will run a particular
operation in Cadence (same one? We don't know!), the whole SPARC
platform is dog slow? Nice. That certainly makes performance
evaluations a lot easier. "My G4 Mac redraws the screen faster than my
POWER4 systems! CHRP is dog slow!"
