I'm not seeing that running Vim 7.3.646 on Fedora 11 under KDE
4.3.1. Both are pretty fast and gvim is even faster than vim.
Running the following in an xterm,
time vim -Nu NONE -c 'silent grep -r house tmp/gvim-grep-test' -cq
I got results typically like these:
real 0m5.128s
user 0m0.487s
sys 0m0.495s
Times running in a GNOME Terminal were essentially the same.
Running the following,
time gvim -f -Nu NONE -c 'silent grep -r house tmp/gvim-grep-test' -cq
I got results typically like these:
real 0m3.459s
user 0m0.610s
sys 0m0.497s
Note that the gvim times are even better than the xterm/vim times,
presumably because of the time xterm needed to write all those lines
to the display. That's even including the time it takes to just
start gvim, which about a second.

Gary
