GNOME Bugzilla – Bug 122871
Gnome-terminal 2.4 very slow.
Last modified: 2005-08-29 12:06:02 UTC
Hello! Gnome ternimal 2.4 works MORE SLOWLY than 2.2? Very slow refresh screen and slow portrayal, slow display of results. I tried gnome-terminal 2.4 from garnome and Ximian Desktop 2.4 unstable. There are ideas as it to correct? Thanks.
Is this on the local machine? What system is it? What hardware? How can we try to reproduce what you're experiencing?
OS: RH 9.0 Local machine: CPU: Intel(R) Celeron(TM) CPU 1000MHz stepping 01 Memory: 251920k/261056k HDD: ST340810A, ATA DISK drive Reproduction: To have Gnome 2.2 install Garnome 0.27. Run Gnome 2.2 and try speed work gnone-terminal 2.2.x Run Garnome and try spped work gnone-terminal 2.4.x gnone-terminal 2.2.x more fast. P.S. Now i install Ximian Desktop Unstable (Gnome 2.4) and install gnome-terminal 2.2.x but NOW this terminal slow as well as 2.4!!! May bug in some library! Thanks for answer!
The terminal widget is in the vte package, but I'm not sure this is enough information to find out what the problem is. What operations are slower than in 2.2.x for you? Could you give some examples and timings maybe?
You have to say _what_ is slow. What command do you run, and what aspect of the terminal is then slow. Are you running screen?
Very simple. I list my home directory gnome-terminal 2.4: $time ls -al real 0m3.192s user 0m0.010s sys 0m0.000s xterm: real 0m1.292s user 0m0.020s sys 0m0.010s gnome-terminal 2.2: real 0m1.951s user 0m0.000s sys 0m0.020s $ls -al | wc -c 16295 if i run mc gnome-terminal 2.4 very slowly draws the screen. In xterm and gnome-terminal 2.2 fastly.
This is probably a long shot, but do you use any binary drivers for the graphics hardware in this machine? I've seen reports of nautilus being slow with nvidia binary drivers before and that just popped into my head now.
No. I not used other binary drivers, only those which were in system. i have internal video card Linux agpgart interface v0.99 (c) Jeff Hartmann agpgart: Maximum main memory to use for agp memory: 202M agpgart: agpgart: Detected an Intel i815 Chipset. agpgart: AGP aperture is 64M @ 0xe0000000 [drm] AGP 0.99 on Intel i810 @ 0xe0000000 64MB [drm] Initialized i810 1.2.1 20020211 on minor 0 Why different versions gnome-terminal have different speed of display? I understand that libraries, but why in the worse party are changed. Others also noticed this problem with gnome-terminal (http://gnomesupport.org/forums/viewtopic.php?p=22405#22405)
I'm seeing this too on my laptop. I'm running gentoo and receintly upgraded to gnome 2.4. The laptop is a Dell Inspiron 8200 2GHz with a GeForce4 440 Go graphics card. I use the latest drives from nVidia. The problem I'm seeing is the line redraw rate. If you cat a file, say /var/log/messages, you can almost see it redrawing each line. This behavior becomes more apparent when you increase the size of the terminal. I hate to do this to you, but I am thinking of switching to gnome from KDE and I know KDE's konsole didn't have this problem (I'm trying to rule out my particular hardward). From within Gnome 2.4, if I cat a random text file (133110 bytes), this is how long it takes: gnome-terminal: 0.421s normal size, 1.645s full screen konsole: 0.133s normal size, 0.232s full screen xterm: 0.102s normal size, 0.085s full screen Notes: normal size is 80x24 and full screen is a little under 1600x1200. Changing the number of lines in history and the color scheme has to affect. My background "Effects" are set to "None (use solid color)".
I'm install FreeBSD 5.1 and Gnome 2.4. Some problem with speed after upgrade from 2.2, but gnome-terminal on my desktop faster than in Linux.

Since I submitted bug 126519 I updated to a newer version of gnome-terminal that no longer shows this problem. It being debian, I have no idea how to get the 'bad' one back. My video card is an old ati rage 128 that seems to behave itself well with linux in general. I generally run 80x70, do not run screen, and have had no speed and/or processor dominance problems with any other xterm (incuding the new gnome-term version I have -- it reports 2.4.2. From my point of view, this is now "fixed."
Strange. I have gnome-terminal 2.4.2 and I have not noticed improvements unfortunately.
No it is not fixed, I have following packages installed: gnometerminal-2.4.2 vte-0.11.10_2 So, testcase reported by me in bug #124544 is still valid: Marking any text area inside gnome-terminal takes several seconds and a lot of CPU, see screenshoot below. Also I have notice that gnome-terminal "eats" too much CPU while idle (do not draw anything, and do not output any text)
Created attachment 22898 [details] top shows CPU eaten by gnome-terminal while selecting text

Here gnome-terminal's scrolling (or displaying) is so slow, that i've got to run with >/dev/null most of my commands, otherwise they take three times longer or more to complete. For example, when compiling a long document in LaTeX: $ time latex project <cut output> real 0m3.839s user 0m0.399s sys 0m0.053s $ time latex project >/dev/null real 0m0.489s user 0m0.352s sys 0m0.029s wooohaa! whats going on?! lets try xterm: $ time latex project <cut output> real 0m0.592s user 0m0.389s sys 0m0.030s $ time latex project >/dev/null real 0m0.438s user 0m0.361s sys 0m0.025s wow! xterm takes 0.592 which gnome-terminal takes 3.839 !?!?!

this bug was opened on "2003-09-21 06:59" and now its 2005. Any luck of getting this fixed (speedy terminal)? it seems that the many features of the terminal have caused it to slow down, maybe if there was an option to disable most of them?
Could you try the tarball here: http://www.gnome.org/~kmaraas/vte-0.11.12.tar.gz and see if that helps?
i just tested vte, and its a bit faster than gnome-terminal. it seems like your 'fix' is to scrap gnome-terminal all together and switch to another application. i dont see a problem with that. if the new terminal runs faster, then so be it.
You misunderstood me. VTE is the terminal widget used by gnome-terminal. You need to compile and install the lib and then try out gnome-terminal performance when using the new version of VTE.
Closing this since it's one of several bugs that talk about general slowness in vte/gnome-terminal. *** This bug has been marked as a duplicate of 137864 ***
