Hello all. I noticed that the Dawn theme was a bit slow to load for me, so I dug into the codebase. I ended up removing jquery and rewriting the javascript (copy-pasting from the Edition theme, to be honest), removing a few js libraries, stripping search out completely, removing the headerbar, and removing some CSS. I also optimised font loading. Loading times have improved quite a bit.
If someone wants to check it out, here is the link to the source. Here is a link to the site I use it on. I absolutely love this theme, and wanted to share my changes with the community. If someone is a bit OCD about site loading time and wants to use Dawn, they might consider using this fork.
