This might be an unrelated problem, but I find that when I copy a large amount of text and paste it into iTerm, it takes a long time to paste. This often happens when pasting into Vim, so it could be a vim issue. For example, copying the code of a Javascript library. When I do this in a text editor outside of iTerm, it's nearly instantaneous.

Vim will type every character you paste, one by one.

F12 should switch you to paste mode and paste it as a block, though on my new Mac this was already mapped to some GUI function so I had to disable that for it to work.

Pasting into a buffer in insert mode is not the best idea. I've remapped <leader>p and <leader>P to paste from the system buffer and it's just as fast as yanking and putting text in Vim.

That doesn't work as well over SSH sessions though, which is where pasting into vim really starts showing its limitations. Vim's normal inefficient behaviour plus a link with latency is an unfortunate circumstance.

Try turning off syntax highlighting and any plugins like jshint that try to operate on a buffer realtime in vim before pasting (or just paste it to an temporary buffer instead of an existing js file) if it's still slow then it's probably iterm and not vim.

I have the same issue, and I know it doesn't happen when using Macvim, so it's probably an iTerm problem.
