line rate
termnetworking
The theoretical maximum a link can carry for a given frame size - and the claim that benchmarking exists to check.
It is a property of the medium and the frame size together, not of the interface speed alone, because per-frame overhead means small frames reach a lower bit rate than large ones on the same wire. This is why a device advertised at line rate may be honest at 1518-byte frames and nowhere near it at 64 bytes, and why any benchmark that does not state the frame size has not stated anything. The number a vendor prints and the number an operator measures usually differ for this reason rather than through dishonesty.
