Turn off the comint-scroll-to-bottom-on-output option. Then type C-p 
when the output starts. The output will go to the buffer, but it will be 
off-screen so the display engine doesn't have to render it. The only 
thing that updates is the scroll bar, because the relative position of 
the window in the buffer is changing, and the mode line's percentage.

You can also switch to another buffer.
