If you've got 100 CPU cores at or near full utilization, you've just saved yourself a CPU core. 100 machines at full utilization, it's a full machine.

The more cores/machines you have, the more this savings means. The threshold "is it worth it?" percentage depends on how many machines saved is worth an engineer's time to do the optimization.
