xterm has extremely poor throughput performance. kitty and most other well designed terminals are atleast 2x as fast as xterm. For example: https://sw.kovidgoy

xterm has extremely poor throughput performance. kitty and most other well designed terminals are atleast 2x as fast as xterm.
For example: https://sw.kovidgoyal.net/kitty/performance/#throughput https://sw.kovidgoyal.net/kitty/performance/#throughput
Of all tested terminals xterm is faster only than konsole.
- jstimpfle 3y agoXterm feels faster to me than all alternatives I've tried (not kitty). I suspect it's input to screen latency. Also, crisp bitmap fonts. Startup is instant too. It has comparatively very good "fidelity", giving usable screen outputs with most applications without tinkering. A factor of 2x in throughput is nothing to sweat about I think, given that xterm is fast enough. Haven't verified the benchmarks in your link, and not tried kitty, but I believe the bench did not test xterm with bitmap fonts which I believe are significantly faster. I'd also look at CPU rasterization performance. I often don't have graphics acceleration available (in a VM).
