Based on the cache suggestions given here: http://xenforo.com/help/cache/ How does one know that cache is working? Specifically, in the first two instances, cache front end and back end file store, is there a place on my server where the files are kept so that I can confirm that things are working? Would the config throw an error if it was not? Also, is file back end store really any better than the built-in Linux (and other nix) automatic caching of virtually all served data? Someone should write up a white paper on ALL these items! Any info welcome!
