# How much does the Falcon Engine cache?

 * I have a large blog (about 4,000 posts and pages) and I am tight on disk space.
   When I tried some other caching solutions, a crawl by a search engine created
   cached copies of all of those pages, amounting to about 2 GB of cached files.
   The site crashed and burned when it ran out of space.
 * Falcon appears to clear the entire cache for many reasons. What I want to know
   is under normal operation, about how long a page should stay cached. My blog 
   has lots of pages rarely accessed except by crawlers (at any given time there
   are usually 4 crawlers on the site), and a few very active pages that are heavily
   commented. Is Falcon going to cache a few pages, or a lot?

 * Hi,
 * Here is the Falcon documentation. It explains manually clearing the cache and
   events that trigger the cache clearing.
 * [http://docs.wordfence.com/en/Falcon_Cache#Cache_Management](http://docs.wordfence.com/en/Falcon_Cache#Cache_Management)
 * I’d say if your content isn’t updated very often then the cache won’t need to
   update very often. You can exclude pages from cacheing as well.

 * I had read the documentation, but I don’t know, not being a WordPress developer,
   when some of those things happen. I also noted the comment that said: “If a comment
   is posted the whole page cache is cleared.” I take “whole page cache” to mean
   the entire cache. My blog gets around 5 comments per hour. Does this mean on 
   average the whole cache gets cleared every 12 minutes?

 * The cache is updated for individual pages when changes are made and not every
   page. What it is saying is that a comment will force that single page to recache
   to reflect the change made by the comment.
 * Hope that helps,

 * I fetched the Cache Stats and it showed that there were 46 pages in the cache
   with the oldest 29 minutes. I added a comment and re-fetched the Cache Stats 
   and it said that there were 2 pages in the cache with the oldest page at 8 seconds.
 * So it appears that adding a comment clears everything in the cache.
 * I personally like this behavior because it keeps the cache small.

 * Thanks for the update. Let me get clarification on “Whole Page Cache.” We may
   need to change it to “Entire Cache” to make it easier to understand.
 * I’m going to mark this as resolved.
 * Thanks!
