How large your output should be to take so long?

The emacs display is notoriously slow. I have fixed this back in
March. We are now caching output in temporary buffers before flushing
into comint buffer every 0.6 seconds. So, the output speed is pretty
much as fast as emacs can get it. To be more concrete I would need a
concrete example.
