Really bad performance in Urxvt
Hi everyone,
I'm having issues with urxvt, it's very lagging (tearing) when displaying a lot of text and it's a lot slower than Konsole or Xfce terminal for example.
I use native transparency. If i turn it off and kill compton, I can get rid of the tearing issue. But it doesn't change the fact that a command like :
cat /usr/share/dict/wordsis soooooo long compared when I do it on another terminal.
I use xf86-video-ati driver if that can help. I use monofur font and Infinality font rendering.
I have been looking for hours in Internet, tried some things but nothing helps so far 
Thanks in advance !

Re: Really bad performance in Urxvt
You need to turn on Vsync in your driver or in compton.
To enable in compton use something like this.
compton --opengl --vsync opengl-swc --paint-on-overlayOffline

Re: Really bad performance in Urxvt
Yes, running compton this way makes tearing go, but it didn't help with the amazingly low performance of urxvt.
For example :
With konsole
time cat /usr/share/dict/words
real 0m4.702s
user 0m0.000s
sys 0m0.343sWith urxvt
time cat /usr/share/dict/words
real 0m51.332s
user 0m0.000s
sys 0m0.600sAsus 1225B - 11,6" - AMD E-60 Dual Core 1,3Ghz - 4 Go RAM - Disque dur SSD 128 Go - Radeon HD6290

Re: Really bad performance in Urxvt
Well the bug afaik is with XFT fonts in urxvt, the vsync thing is just a work around. You could try disabling XFT fonts to see if that is the issue you are having, it may be something different for you.

Re: Really bad performance in Urxvt
Switching from monofur to termsyn and disabling native transparency helps, but didn't get close to the amazing speed I have with urxvt on my other laptops (xft font and transparent too)

Re: Really bad performance in Urxvt
I would think it is a driver issue then. Try disabling vsync in compton then enabling in the driver itself. Otherwise I run urxvt with all the bells and whistles using the Catalyst driver (14.1) with no issues.

Re: Really bad performance in Urxvt
I even tried without compton and nothing changes. I also can run a live usb with free drivers and no problems, the command ends in 1 second with urxvt, even faster than Konsole in my previous tests, si there's definitely something wrong with my config. Can it be Infinality fonts ?

Re: Really bad performance in Urxvt
is this an Arch Linux system, or is it a fork like Manjaro?

Re: Really bad performance in Urxvt
No, it's Arch Linux. I had Manjaro before, and I never had this behaviour, it's very strange.

Re: Really bad performance in Urxvt
This is strange. Have you tried creating a new user without any customization and seeing how it performs?

Re: Really bad performance in Urxvt
I have never tried many of those settings. I would suggest a binary search -- comment out about half of them, and see if it improves. If it doesn't. then the ones you commented were not at fault. Uncomment them, and comment half the ones you did not try before; lather, rinse, repeat...

Re: Really bad performance in Urxvt
It seems that transparency si responsable, at least for the most part. I still don't understand as I didn't have this behaviour on other but similar configs. Maybe a driver issue but everything is working fine except this.
