Really slow xterm

[cothrige <cothrige@bellsouth.net>]

I have installed xterm via apt, running etch, and have noticed that it
scrolls really slowly.  I compared it to rxvt by running `time ls` in
/usr/bin with rxvt taking 0.572s and xterm running at 4.633s.  Earlier
it was even worse taking over 10 seconds.  It is a very big difference
in usage, and if I am compiling something it can have very significant
impact.

Has anybody else had this experience?  Is there anything I can change
which may help this?

Thanks in advance,

Patrick
