Well, in the mainframe world, people don't typically measure in MIPS or FLOPS for day-to-day work. It's all about efficiency and throughput. We care about actual elapsed time, and resource consumption rather than some abstract benchmarking metric. Part of this is because a batch job will NEVER get 100% of the CPU, because it is sharing the system with so many other processes.

- lostmsu 7y agoElapsed time is the typical benchmarking metric, used, for example, by the language benchmarks game. Not sure what "abstract metrics" are you referring to.

- lostmsu 7y agoI know what latency and throughput are. I am asking what "abstract metrics" previous commenter was referring to as opposed to these.
- 6thaccount2 7y agoThanks for the helpful background. I think what I said still stands though. In the PC world, my computer has a certain number of FLOPS even though it has no impact on my day to day work where I care more about RAM and such.
