After running a few deployments, I was concerned that the deployment process was a little slow. On closer inspection, the default Dreamhost setup for Wordpress comes with 50 themes. This is great functionality, but 49 of them are not used at any one time, and should be removed once you’ve picked the one you want to use.
For my configuration, I kept the default theme, the one I picked as a base for my site, and a copy of that theme I will make changes to as I need.
This reduces the size of my deployment from over 15MB to less than 4MB, and my deployment time is now a lot faster.
