Steve,
I ran another test with a different font in RXVT, and got very different
results:
New RXVT test:
...\rxvt.exe -g 120x91+853+0 -bg #000055 -fg #eeeeee -fn "Andale Mono-12"
-sr -sl 5000 -vb -e /bin/bash --login -i
% time ls -lR /
real 0m32.422s
user 0m5.920s
sys 0m21.781s
% tsize
rows 92; columns 120
(Note that I invoke rxvt requesting a 91-line-high window and get a 92
line-high window. This off-by-one always happens to me with RXVT, for
whatever reason--see below.)
Previous RXVT test:
...\rxvt.exe -g 120x99+732+0 -bg #000055 -fg #eeeeee -fn "Lucida
Console-11" -sr -sl 5000 -vb -e /bin/bash --login -i
% time ls -lR /
<lots of elided output>
real 1m33.360s
user 0m6.765s
sys 0m31.561s
% tsize
rows 100; columns 120
Previous Windows Character Subsystem window:
...\bash.exe --login -i
% time ls -lR /
<lots of elided output>
real 1m27.782s
user 0m7.296s
sys 0m23.608s
% tsize
rows 93; columns 120
In the previous test, the windows were nearly the same size (in pixels). In
the second case the choice of font yielded a closer match to the character
cell dimensions of the Windows Character Subsystem window, but the RXVT
window size in pixels was about 15% narrower and the Character window. In
all cases, the windows very nearly (or exactly) filled the screen's 1200
vertical pixels less a double-high "bar" (single-height taskbar +
single-height quick-launch bar).
Performance measurement is _never_ simple or straightforward!
