From Cobol, to the IBM mainframe, to C, to x86, these high-tech senior citizens not only keep kicking but provide the foundations for many vital systems that keep IT humming.

I dont understand people that dont understand what I claim. I have ONLY said that Mainframes cpus are weak. I dont understand why people would want to say "hey, our Mainframe can handle lot of I/O - you are wrong!". No, I am not wrong. I have never talked about their I/O, I have been talking about their CPUs. Please read my posts again.

Their CPUs may be slow by some measures, but if that was a concern, the architecture would simply change.

Mainframers like myself never speak in terms of CPU power because that is not a design consideration for a mainframe system. Bringing it up serves no purpose, really. What's the point? Get a supercomputer if you want to do number crunching .. that's what they're designed for.

Your statement about CPUs is much like criticizing a freight train because it can't accelerate quickly. Yeah, that's true. So? ;)
