I use for a while the plugin Faster DokuWiki Plugin,
fastwiki with bootstrap template and it speeds up really giving to the whole (DokuWiki with Bootstrap3) a much better user experience. As I have about 80 plugins installed with some important ones (like Struct, bureaucracy..) I've tested it on a local wiki for months before activating it on production. I just keep the defaults settings of fastwiki and never met an issue. A nice and useful plugin.
