Why is pasting a long one-liner very slow in Vim's insert mode?

Question

My Macbook was stuck yesterday, when I tried to paste 1200 lines of 80 characters to Vim. It was much faster to download the file, and not to paste the text.

But if it's on the web, you should have tried:

:e http://link/to/file 

Then if necessary save it as a local file.

And if it's slow because of the redrawing, look at this option:

            *'lazyredraw'* *'lz'* *'nolazyredraw'* *'nolz'*
'lazyredraw' 'lz'   boolean (default off)
            global
            {not in Vi}
    When this option is set, the screen will not be redrawn while
    executing macros, registers and other commands that have not been
    typed.  Also, updating the window title is postponed.  To force an
    update use |:redraw|.

And if it's a local file, then pasting is not necessary: try

:read file 

instead.
