Package: xterm Version: 4.3.0-7 Severity: normal
Please include the analagous patch that suggested and tested here (for multi-gnome-terminal) into xterm (and send upstream - why didn't reportbug ask me the upstream question this time?): http://www.uwsg.iu.edu/hypermail/linux/kernel/0404.0/0467.html In kernel 2.6, the scheduler changes have uncovered a bug in xterm that make the scrolling speed hideously slow[1] because it causes xterm to output one character at a time in a busy loop instead of jump scrolling. This will affect all terminals based on xterm, which is well, all of them. Presumably upstream will include this, but they don't seem to have done so yet[2][3], so I am submitting this bug report. [1] To demonstrate, open up an xterm to maximised, `ls -trlA --color` a big directory - say the 500 files in your home directory. See how slow. Now pipe the same through `cat` or `dd`, and see how quick. You may need a slow (~500MHz) computer to appreciate the full effect of just how hideous this is (6-10 seconds on my machine). [2] At least, xterm is still as slow as normal for me, but I can't download the xterm sources myself and verify yet, because hey, 50MB [3] the poster of the patch said it was in debian unstable already - I presume he meant only for gnome-terminal, because I just upgraded to test for the existance of this patch -- System Information: Debian Release: testing/unstable APT prefers testing APT policy: (990, 'testing'), (50, 'unstable') Architecture: i386 (i586) Kernel: Linux 2.6.4 Locale: LANG=en_AU, LC_CTYPE=en_AU Versions of packages xterm depends on: ii libc6 2.3.2.ds1-11 GNU C Library: Shared libraries an ii libexpat1 1.95.6-8 XML parsing C library - runtime li ii libfontconfig1 2.2.2-1 generic font configuration library ii libfreetype6 2.1.7-2 FreeType 2 font engine, shared lib ii libice6 4.3.0-7 Inter-Client Exchange library ii libncurses5 5.4-2 Shared libraries for terminal hand ii libsm6 4.3.0-7 X Window System Session Management ii libxaw7 4.3.0-7 X Athena widget set library ii libxext6 4.3.0-7 X Window System miscellaneous exte ii libxft2 2.1.2-5 FreeType-based font drawing librar ii libxmu6 4.3.0-7 X Window System miscellaneous util ii libxpm4 4.3.0-7 X pixmap library ii libxrender1 0.8.3-5 X Rendering Extension client libra ii libxt6 4.3.0-7 X Toolkit Intrinsics ii xlibs 4.3.0-7 X Window System client libraries m ii xlibs-data 4.3.0-7 X Window System client data -- debconf information: * xterm/clobber_xresource_file: true xterm/xterm_needs_devpts:
