I’ve been using my old static site generator setup for years now, when I first started using DocPad it was fast, simple and had the ability to add plugins which made it immensely extensible. However since then development has died down and there have been some questions about how long the development will continue, my site has become more complex requiring a number of additional plugins, and the general performance of DocPad seems to have slowed down (mostly due to the additional plugins ect.)
