Finding bottlenecks in the source tree


Often, the development teams know where the bottleneck in the source tree is, but it can be challenging to convince the management that you need resources to rewrite some code. However, with Git, it is fairly simple to extract that type of data from the repository.

Getting ready

Start by checking out the stable-3.1 release:

$ git checkout stable-3.1
Branch stable-3.1 set up to track remote branch stable-3.1 from origin.
Switched to a new branch 'stable-3.1'

How to do it...

We want to start by listing some stats for one commit, and then we can extend the examples to larger chunks of commits:

  1. The first option we will be using is --dirstat for git log:

    $ git log -1 --dirstat
    commit da6e87bc373c54c1cda8ed563f41f65df52bacbf
