Trivial terminal speed benchmark

Today, while playing with st, I tried a very simple benchmark. Here it is:

$> time seq -f 'teeeeeeeeeeeeeeeeeeeeeeeeeeeeeest %g' 999999

Here are the results:

xterm: 0m28.508s
rxvt: 0m8.568s
st: 0m12.082s

All the terminals shared the same fonts, but xterm and rxvt had saveLines=1024 set for scrolling purposes, feature that st lacks.

Being st at such an early stage of development, I think this is a good result.
