Storage is the new DASD and CPU time is the new wall clock time.

I like it.

so such accounting measuring CPU time (elapsed instruction time) is
analogous to early accounting which measured by elapsed wall clock time.

cache miss/memory access latency ... when measured in count of processor
cycles is comparable to 60s disk access when measured in in count of 60s
processor cycles.
