Is anyone still having this issue with color escape sequences? I'm seeing a huge slowdown when I use xft fonts and color escape sequences in my terminal. I'm running xorg 1.9, and I found similar results on a computer running Nvidia binary driver as well as an ATI machine.
With color:
time seq -s `echo -e "\033[32mGreen\033[0m"` -f "%g" 100000
Xterm, no custom settings: 0.429s
urxvt, default font: 0.481s
urxvt, xft:inconsolata-10:antialias=false: 30.710s
urxvt, xft:inconsolata-10:antialias=true: even worse, didn't wait
No color:
time seq -s `echo -e "White"` -f "%g" 100000
Xterm, no custom settings: 0.173s
urxvt, default font: 0.160s
urxvt, xft:inconsolata-10:antialias=false: 0.158s
urxvt, xft:inconsolata-10:antialias=true: 0.3877s
Could someone who uses xft try some of these benchmarks?
Edit: It is the changing escape sequences that are the problem, printing only text of a different color is fast.

'time seq -s `echo -e "White"` -f "%g" 100000' run for 26 seconds here - the cpu meter in htop was maxed.
'time seq -s `echo -e "\033[32mGreen\033[0m"` -f "%g" 100000' took over a minute.
I'm using
urxvt*font: -*-terminus-medium-r-*-*-12-*-*-*-*-*-*-*
xterm with default font was fast in both cases.
