If I enabled XF's file based caching in config.php, what exactly would the consequences be? I can't see a list of what sort of things it would cache. We've got opcache/wincache enabled, so perhaps using the file cache would be advantageous. It may be nice to enable css minify, but we don't have any of the other caching mechanisms available, so file cache is our only option at the moment. However, if enabling the filecache would mean that lots of other things are also cached this way, then it may be slower overall. I'd be interested to hear what other file cache users think!
