> xterm does direct rendering via Xlib, which is the primary reason it can be so fast in responding to user input. This is also the reason why its throughput is, on the other hand, rather poor.
My guess is the rate at which stdout from a process shows up in the terminal?
I think Terminal.app on macOS is likely the inverse of this… it likely has a fair amount of input lag, but holy moly can it handle a lot of output being dumped at once without breaking a sweat.
I thought terminal.app has very short latency, looking back at the benchmarks written about here https://danluu.com/term-latency/. Terminal.app’s latency measures around 5ms beating most other terminals. (It’s a shame it still doesn’t support true color.)
What's throughput in this case?
