do ruby plugins make starting vim very slow?

Question

Lately vim takes a long time to start up when I'm running it to edit a ruby file or a rails project. But it starts up fast when invoked on a plain text file. Is there any way to find out which ruby vim plugins are most responsible for prolonging the startup?

Answer 1

If you're using version 7.2.286 or newer, you can run vim --startuptime vim.out foo.rb to log how long the various parts of the startup process take.
