I have a big project with data files, loads of includes and sass, but my project takes 12-15 seconds to reload is there a way to only get jekyll to cache pages your not working on etc.

Have you tried using incremental builds?

> [**Incremental build**](https://jekyllrb.com/docs/configuration/#build-command-options)

Enable the experimental incremental build feature. Incremental build only re-builds posts and pages that have changed, resulting in significant performance improvements for large sites, but may also break site generation in certain cases.

> `jekyll build --incremental`

No not exactly. You can use the `--incremental` flag with `jekyll serve` too. Or you can enable it for both `build` and `serve` by adding `incremental: true` to your \_config.yml file.

You may experience strange things using it though. Because of the way it caches files things don’t always behave how you’d expect. If you have a fairly simple site you’ll probably be OK.
