    On of the features you might want to use for your situation,
though, is make sure "jump-scroll" is turned on if it is not.
Otherwise any terminal program might take a very long time to catch
up.  It really is an expensive operation to scroll text on a remote
machine.  Early HW terminals and PC screens used special hardware
to perform scrolling at fast speed.  Performing a smooth scroll
via bit-moves of memory would be VERY painful on older machines
or current machines using a slow-enough remote interface.
Mintty does not support smooth scrolling. (I gave it a try once but there is no complete implementation.)

    Try running xterm locally and make sure TERM is set correctly on the remote machine and I think you may be happier
with the performance and "feel"...
A good suggestion anyway.
However, if you provide instructions on how to reproduce the issue, I may find time to check out whether there is some improvement potential.
