I agree. Imagine a compute intensive business with some cannibalized
CPUs in a drawer and some idle machines sitting around. Of course,
they run NetBSD. The company has already taken the time to benchmark
various important apps they run with various CPU types/speeds.
They've controlled for other variables by fitting out their machines
similarly or identically in terms of RAM, bus, etc. When the company
needs to replace machines on their network or a CPU in a particular
machine, it would be nice for them to get information about what kind
of CPUs are in their boxes or drawer without resorting to the measures
In general, I'm always suspicious of statements that a particular
piece of information can't possibly be important to you.
All the best,
