I'm using https://github.com/carlhuda/janus vim distribution and clearly not satisfied with load time.
What would be the best way to profile and speed-up vim load time? Also would be interesting to compare load time with http://vim.spf13.com/
If you just want to see what's consuming start up time, then you can use the
vim --startuptime timing.out
The file will look like this:

You can debug startup time by using the built in Vim profiler (tutorial)
If your version of vim is compiled with
:profile you can run:
vim --cmd 'profile start vimrc.profile' --cmd 'profile! file ~/.vimrc'
If not, your stuck debugging it manually by adding and removing plugins and seeing where the long startup times are coming from.
I personally don't recommend using a Vim distribution. If you don't know what every line in your
.vimrc is doing, then it becomes difficult to track down problems, or find where two plugins happen to conflict. For my personal configuration, I've spent a few months adding and removing plugins, finding which ones work for me and which ones don't. Vim is highly customizable, so take advantage of the fact that it can be configured to work perfectly with your workflow.
