Nobody uses "performant" to refer to any of those. It usually means either high throughput, or some aggregate of high throughput + low latency + low memory usage.

Thanks for the response - from my perspective the most meaningful measurement of "performance" (basically "efficiency" but also throughput) is computation per unit of energy (and heat which has to be dissipated), but memory efficiency is also important, as is tail latency in certain cases.

What does "Rust is roughly as performant as C" mean, do you think?
