Konsole is faster than Alacritty, but much easier to configure.

uxterm is the fastest.

    Latency in milliseconds

    Program    mean  std  min   90%   max
    uxterm     1.7   0.3  0.7   2     2.4
    mlterm     1.8   0.3  0.7   2.2   2.5
    Konsole    13.4  1.2  11.5  15    16.1
    Alacritty  15.1  1.2  12.8  15.9  26.3

Those Alacritty numbers look an awful lot like reporting framerate tuning rather than underlying performance (16.6ms latency being one frame at 60hz).

Unsure how that was measured, but I'd like to see urxvtd up there. I'd bet a beer it's statistically significant faster. :)
