Profiling Vim startup time

I’ve got a lot of plugins enabled when using Vim – I have collected plugins over the years. I’m a bit fed up with how long Vim takes to start now, so I’d like to profile its startup and see which of the many plugins I have are responsible.

Is there any way to profile Vim’s startup or script-running? Ideally I’d like to know how long Vim spends in each Vim script it loads.

If you're using Vim 7.2.269 or later, then there's the --startuptime option you can use.

vim --startuptime vim.log

from the help (vim -h):

--startuptime <file> Write startup timing messages to <file>
