Unfortunately, that's not enough: I have to know which files have changed and how (created, deleted, modified).
Also I feel that it's not the size of the output which is slow - the scan of directories itself is.

I'm developing a plugin for Git integration for IntelliJ IDEA (an IDE for Java and other languages).
And the task I'm working now is to get the status of index and working tree. I want to make it as fast as possible.
To work with a Git repository I start a process with git native commands, so every command to execute is additional cost.
(Maybe I could work with the filesystem and raw Git repository, but it would be an overhead).

If we forget about "git status --porcelain" there is no single command to get the whole status. I could use 
"git ls-files -ov" for unversioned files + "git diff --name-status" for all other.
OR 
"git ls-files -douvm" for the changes in the working tree + "git diff-index --cached" for the changes in the index.
OR
"git ls-files -ov" for unversioned + "git diff-files" for other files in the working tree + "git diff-index --cached" for the changes in the index.
or maybe something else

I've made a script which executes these commands (which allow to get the total status) on a large repository many times. 
My results show that "ls-files -douvm"+"git diff-index --cached" is the fastest combination.

Do you think I could achieve the same result in a simpler or faster way?

Thanks a lot.
