Well, I don't mean to.  ":set" says this:

--------------
autoindent      helplang=en     scroll=11       t_Sb=Esc[4%dm
backspace=2     history=50      ttyfast         t_Sf=Esc[3%dm
cscopetag       hlsearch        ttymouse=xterm
cscopeverbose   ruler           viminfo='20,"50
cscopeprg=/usr/bin/cscope
fileencoding=utf-8
fileendcodings=utf-8,latin1
formatoptions=tcql
--------------
So, do I have syntax highlighting enabled? The t_Sb and t_Sf look suspiciously like formatting commands, but I confess I'm not conversant on vim options.

Thanks,

Max

I created and opened a file as follows:

  while true
  do
  echo '123456789012345678901234567890123456789012345678901234567890'
  done | head -2000000 > two_million_lines
  vim two_million_lines

Then within vim executed:

  50%
  :.,$d

Using vim 7.1 under Cygwin and Windows XP on a 3.6 GHz Pentium with
2 GB of RAM:  9 seconds.

Using vim 7.1 under Red Hat Enterprise Linux WS release 4 on a 2.8
GHz Pentium with 500 MB RAM:  16 seconds.

Regards,
Gary
