From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i586; en-US; rv:1.0.1) Gecko/20020809 Description of problem: I have tried konsole, and gnome-terminal, and both have extremely slow screen updating, especially in 'ls' or 'ps', or 'cat' type commands. Running xterm works fine. I suspect it has something to do with the anti-aliasing being done? Version-Release number of selected component (if applicable): gnome-terminal-2.0.1-2 kdebase-3.0.3-3 How reproducible: Always Steps to Reproduce: 1.open konsole and gnome-terminal 2.'cat /var/log/messages' 3. Open xterm 4. 'cat /var/log/messages' Actual Results: Notice the slow window update under konsole and gnome-terminal Notice that xterm performs normally. Additional info:
Not an XFree86 bug. Reassigning to gnome-terminal since it was listed as being slow.
This problem is also evident in KDE's konsole terminal. And it shows up when in either GNOME or KDE desktop.
I am having a similar problem except for me, konsole, gnome-terminal, and xterm are all slow. For me xterm is extremely slow. When I issue the command: ls -l /dev it takes 42 seconds for xterm to finish the directory listing under KDE. Under gnome, the same command took 2:40 to complete in xterm. When I'm not running X-windows, the same command takes less than two seconds to complete from the console. From konsole, the same command took 24 seconds and from gnome-terminal it took 16 seconds. I do not believe this is a problem with konsole or gnome-terminal since it happens in both and I've had the problem xterm too. When I run top while running the command, X is using the majority of the CPU. FYI, it may or may not be related... the computer that I'm having this problem with is one of the computers for which X stopped installing correctly between versions 7.2 and 7.3 due to support for S3 968 video controllers. It still didn't install correctly in redhat8, but I used the generic vesa driver as recommended in response to my bug report #65629.
Using the generic vesa driver you won't have hardware acceleration, which probably means pretty much everything is going to be slow to some degree. X using most of the CPU suggests that's the problem.
Try using 'xterm -j -s' which enables 'jump scrolling'. Works for me. gnome-terminal should really get this feature.
I was experiencing the same problems with Konsole. I have changed the font from 'Monospaced' to MiscFixed which gives a considerable speed improvement.
