I've tried kitty, alacritty, ghostty, wezterm, and konsole (all on X11), but I keep coming back to xfce4-terminal because it opens near instantly and has the least input latency of any of the other terminal emulators I've tried. It also uses very little memory in comparison (with 6 windows open and a fair bit in each scrollback buffer): Private + Shared = RAM used Program 31.2 MiB + 10.7 MiB = 42.0 MiB xfce4-terminal

I was curious to see what the actual latency was, so I used Pavel Fatin's https://pavelfatin.com/typometer/ https://pavelfatin.com/typometer/. Notes: This system is running Arch, with kernel 7.0.3, scx_bpfland, and i3 on X11. Primary GPU is an integrated Intel GPU.
