If I cut/paste into octave, it is slinky, a few char appear, a delay, a
few more char, etc.

If I do this with any other xterm, cut/paste seems instantaneous.

I configure with
../octave/configure F77=gfortran --no-recursion

and make produces no errors.
make check seems Ok.

If I start octave with
/usr/local/bin/octave, I get the gui, so I use
/usr/local/bin/octave --no-gui

Actually, I use

/usr/bin/xterm -j -sk -sb -sl 1000 -fn 9x15 -bc -bg white -fg black
-geometry 80x55 -e octave --no-gui&

from an alias.

Is it possible that allowing qt in the build that I have introduced a
problem with readline?

To answer the question, If I build octave with qt and start it without the gui, then, cut/paste is slinky.

If I build octave without qt and start it normally, cut/paste is instantaneous.

Seems to be a problem with readline/qt interaction.
