When this happens, I usually redirect the whole output to a file and
then view it in emacs with `auto-revert-mode'. 

Btw, Emacs can manage large buffer; in my experience, the culprit is
often the fontification process (especially if you use
slime-presentations), because Emacs redoes the fontification each time
the buffer is updated, you can test this by disabling fontification (M-x
font-lock-mode RET) and see if you see some improvement.

For example, when I use M-x compile, I disable the fontification until
the compilation is done to avoid freezing my emacs.
