Cobol Still Powers the Global Economy

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.

Elapsed time is the typical benchmarking metric, used, for example, by the language benchmarks game.

Not sure what "abstract metrics" are you referring to.

fyi

"Measurements of performance" https://www.ibm.com/support/knowledgecenter/en/SSGU8G_14.1.0...

I know what latency and throughput are. I am asking what "abstract metrics" previous commenter was referring to as opposed to these.

Thanks 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.
