Here's a sample comparison of "man" versus "info" on my system (relevant as help-texinfo@xxxxxxx is being copied into this discussion): $ time info gcc > temp real 0m0.112s user 0m0.085s sys 0m0.017s $ ls -l temp -rw-rw-r-- 1 g g 3.0M Apr 7 20:14 temp $ time man gcc > temp troff: <standard input>:11612: warning [p 111, 6.0i]: can't break line troff: <standard input>:11660: warning [p 111, 13.8i]: can't break line real 0m0.620s user 0m1.004s sys 0m0.114s $ ls -l temp -rw-rw-r-- 1 g g 1.2M Apr 7 20:16 temp I find the startup of "info" to be instantaneous, whereas man pages often have a noticeable delay. Doubtless man would have more comparable runtimes were cat pages being used. Being able to reformat the text for arbitrary widths is of limited use, in my opinion, as text becomes more unreadable at long line lengths. I suppose cat pages could be provided in a series of sensible widths. (The same is true in theory for Info, but I've never heard of anybody using widths for Info output other than the default 72 columns.)
