Cost per unit of work
Compare hardware in $ per unit of work, not $ per hour.
Worked examples, recomputed
Every number the mechanisms quote for this relationship is recomputed from it, so none of them disagrees with it.
- 2.5× the hourly price, 3× faster → 0.83 per job
- 2× the throughput at 3× the price → 50% more per unit of work
Where it appears
Each mechanism states it in its own names. The general symbol each name stands for is shown with it.
- Scheduling & Workload Management
Which work runs now, which work waits, and who pays for the waiting?
