It turns out that this Red Hat installation also has vim 6.3.82 in /usr/bin/vim, so I tried that, too. /usr/bin/vim -u NONE two_million_lines 50% :.,$d 2 minutes 30 seconds! Eureka! According to the System Monitor CPU bar color, that was almost all User time, whereas with vim 7.1, it was a more balanced mix of User and Kernel time. (Kudos to Bram for such a performance improvement from vim 6 to 7!) I'm not allowed to update anything under /usr on this system, either, so I build the latest and greatest versions of tools under $HOME/src and put the binaries in $HOME/bin. Building vim under Linux is really easy. I do the following. mkdir ~/src/Linux/vim-7.1 cd ~/src/Linux/vim-7.1 Download vim-7.1.tar.bz2 from vim.sf.net. tar jxf vim-7.1.tar.bz2 cd vim71 ./configure --prefix=$HOME/src/Linux/vim-7.1 --enable-cscope make make install ln -s $HOME/src/Linux/vim-7.1/bin/vim ~/bin/Linux/vim My PATH includes $HOME/bin/Linux and that directory contains most of the symbolic links to vim that you will find in $HOME/src/Linux/vim-7.1/bin; the ones I use. That is, $ cd ~/bin/Linux $ ls -l | grep vim lrwxrwxrwx 1 garyjohn fw 3 Nov 14 2005 gvim -> vim lrwxrwxrwx 1 garyjohn fw 3 Nov 14 2005 gvimdiff -> vim lrwxrwxrwx 1 garyjohn fw 3 Sep 23 2005 vi -> vim lrwxrwxrwx 1 garyjohn fw 3 Sep 23 2005 view -> vim lrwxrwxrwx 1 garyjohn fw 40 May 17 18:45 vim -> /home/garyjohn/src/Linux/vim-7.1/bin/vim lrwxrwxrwx 1 garyjohn fw 3 Sep 23 2005 vimdiff -> vim That makes it really easy to update and to test different versions of vim with only a change to one symbolic link. But that's just a matter of taste. The point is that however you choose to install it, it's easy to build and maintain your own vim installation without having to bother or bother with your system administrator. > I went looking for release notes for vim, but the announcements I found > didn't go into detail about what bugs were fixed in which version.

Or you can just go that page directly, http://vimdoc.sourceforge.net/htmldoc/version7.html This describes all the changes from version 6 to version 7, including bug fixes.
