When I was setting up the development environment. Setting up included installing programs using the package manager home brew.
I didn't notice a difference in wait time (this is subjective) from my ivy bridge rMBP.
You might notice it if your not using a rMBP or using the previous 13 inch one.
Oh I'll be coming from a 2010 MBP with a 330M; it will be a bit of an upgrade
