The Falcon engine does a great job at making my site's response times fast, but it doesn't seem to be caching the home page, which is the page that is visited the most often.
Why isn't it caching the homepage? I see the file for the homepage in the cache directory, but the server still responds in ~200 ms, which is usual for a non-cached page (it's a good dedicated server, in case you are wondering why it is so "fast"). All other pages, like /blog/, /contact/, /2014/04/, etc, respond in ~50 ms.
