If you're going to run a benchmark, at least post the results. I was planning on writing up a different blog post about the terminal optimization journey, but I actually used `kitten __benchmark__ --render` quite a lot to optimize it:

rune --version Rune v1.2.1 (HEAD is 40bf9cc1)

Results: Only ASCII chars : 1.13s @ 177.2 MB/s Unicode chars : 1.44s @ 123.2 MB/s CSI codes with few chars : 2.95s @ 33.9 MB/s Long escape codes : 6.25s @ 125.5 MB/s Images : 2.76s @ 193.1 MB/s

/Applications/Alacritty.app/Contents/MacOS/alacritty --version alacritty 0.13.1 (fe2a3c5)

Results: Only ASCII chars : 1.97s @ 101.4 MB/s Unicode chars : 1.26s @ 140.3 MB/s CSI codes with few chars : 1.26s @ 79.3 MB/s Long escape codes : 5.22s @ 150.1 MB/s Images : 1.34s @ 399.3 MB/s

ghostty --version Ghostty 1.3.2-main-+aa21caeaa

Results: Only ASCII chars : 354.9ms @ 563.5 MB/s Unicode chars : 815.42ms @ 217.0 MB/s CSI codes with few chars : 1.23s @ 81.6 MB/s Long escape codes : 6.39s @ 122.8 MB/s Images : 680.84ms @ 783.4 MB/s

Ran just now, on a Macbook Pro M4 Max 128Gb.

Rune doesn't support the kitty graphics protocol, so ignore the Images bench results.
