 Posted: Wed Jan 02, 2013 5:43 pm Post subject: xterm 3% cpu usage, urxvt 40%, WHY???? |
 |
|
hi,
urxvt seems to have a problem with its rendering engine. Something as simple as playing a song with mplayer that displays this on the terminal:
| Code: | | A: 0.6 V: 0.6 A-V: 0.005 ct: 0.029 0/ 0 12% 0% 2.2% 0 0 |
with urxvt xorg process X goes up to 40%, when I do this with xterm xorg X process stays at 3%.
How can this be??
my current rxvt-unicode USE flags are:
| Code: | 256-color alt-font-width fading-colors focused-urgency font-styles iso14755 mousewheel perl
unicode3 xft -afterimage -blink -buffer-on-clear -pixbuf -secondary-wheel -startup-notification -vanilla -wcwidth |
I want to fix this once and for all. Whatever urxvt is doing sometimes causes to crash the shell even.
If anyone know where I can start looking at this matter I'd appreciate it much.
thnks |

I have no idea but perhaps have some ideas... Are you using transparent background?
What about if you did something "find /" in a window, which uses more CPU - urxvt or xterm?
What video card are you using? And driver? Is it accelerated?
Do vte-derived terminals (like gnome-terminal) behave badly too?

Xterm have 4 differents USE flags and rxvt-unicode have 18. That's make rxvt-unicode surely less light then xterm. Try to compile rxvt (4 USE flags) to see if it use less resources than rxvt-unicode. Try to disable selectively rxvt-unicode USE flags to find out which one consume most resources.
