Konsole already does what you describe.  Repeated updates are buffered and only
sent to the screen at periodic intervals.  However, there is still a cost to
updating the screen periodically and processing all the changes received from
the terminal.

> For example, this slowdown was caused by konsole: user=20152ms
> sys=403ms wall=73273ms

That doesn't tell us much.  If you have a benchmark you need to provide
instructions sothat other people can follow to reproduce it.

That is not just a 'workaround', it is the right thing to do.  If you actually
care about what is output to the screen and what to search it, filter it or do
some other analysis of it then that is a lot easier if the content is written
to a file.
