There may not be a real performance effect, but there is a definitely 
perceptible latency.  You see it, right?  I'm glad to know it's not 
actually interfering with processes, though.

Steve,

 From BASH in a Windows Character Subsystem window:

% time ls -lR /
<lots of elided output>
real    1m27.782s
user    0m7.296s
sys     0m23.608s

% tsize
rows 93; columns 120


 From BASH in RXVT:

% time ls -lR /
<lots of elided output>
real    1m33.360s
user    0m6.765s
sys     0m31.561s

% tsize
rows 100; columns 120


% time ll -lR / |wc
   20812  173469 1309196

real    0m29.375s
user    0m5.982s
sys     0m23.169s


In both cases the window was unobstructed. I have a Matrox G400 MAX.

It's evident visually that the scrolling algorithm is somehow different,
though I can't say how, really.

Nonetheless, there isn't much real difference in performance, at leat on my 
system.
