Surely not :( > Without knowing the hardware & software setups, I can believe this. Why? Because our distributed systems people "proved" that a Sun running Solaris was faster than z/Linux on a z. Of course, they were comparing a _dedicated_ Sun server (don't know the exact model) which 10 CPs and 10Gb of memory to z/Linux running on a z890 with 2 Gb memory and a single IFL. Kind of like proving that a Chevy is better than a Mazda by comparing a Corvette's performance on a race track to my Mazda 3 on the same race track. > > > -- > Wayne V.
