I’d suggest to build a custom image and use only the recipes you need for your application. I mean, when the Edison boot up, it takes time to boot all the recipes included in the default image, so if you build a custom image using only the necessary recipes for your application, the Edison will boot up faster.
In order to build an image I suggest read the BSP (Board Support Package ) and the Yocto Proyect Manual (http://www.yoctoproject.org/docs/1.7.2/mega-manual/mega-manual.html) as well.
Hope this information helps.
