Re: How are CPU Speed and Overall CPW Related?

You are gonna hear this a LOT: "It depends"....

Might I suggest, "Forget clock speed", 100mhz & 200mhz are different
numbers
but depending on the application, one "might" outrun the other one part
of the
time... I have seen very few CPU bound jobs in many years of this.

It very well might run faster, since the machine has more memory, it
will
spread the joy out to all users, so all jobs could very well finish
earlier.

You bet your template there is a governor(wildly misunderstood) that
balances
system resources and that same governor also "might" slow down certain
jobs.

You can perform some "minor" adjustments, but real tuning requires a lot
of
time and study by somebody who understands the results of performance
data.

Performance is black magic on a good day and in my opinion, very few
folks 
have a complete understanding of it(outside of the plant).
