 * Hello
   I have been using this plugin for a few days and I want to share my opinion.
   1- The cache section has flaws that when you update an article, comment, page
   or post, the entire system cache is emptied by default, and this is not good 
   at all.2- The pre-loading part does not work properly and if you choose the number
   of pre-loading pages less and choose the time more, it will not pre-load all 
   pages
 * I have to select almost a thousand pages in each preload and select the preload
   time 1 second each time, which put a lot of load on the server and I get a 503
   error.
 * The problem occurs when your time cache is low and something is updated, the 
   entire cache is cleared.
 * 3- In some cases, preloading cache is not done correctly, which is due to server
   resources.
   When I want to clear the cache of a specific page, it does not work
   properly and I have to clear the entire cache.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fpre-load-problems%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hello [@davod473](https://wordpress.org/support/users/davod473/)
 * Thank you for reaching out and I am happy to assist you with this.
    1. When any page or post, comment is updated, the W3 Total Cache only purges the
       page in question and not the entire cache. If the entire cache is purged, something
       else amy be calling the w3tc_flush_all, and this may be some theme or a plugin.
       
       You can check this using the [Purge log](https://www.boldgrid.com/support/w3-total-cache/purge-cache-log/)
    2. As for the Cache preloading, if you are relying to wp-cron, you may encounter
       problems like this if the cron is not fired for some reason. In this case, the
       next batch of the pages may not be preloaded and this is related as you mentioned
       to your server. Again, check the purge log and see what is calling the flus_all,
       as W3TC does not flush all cache once the page or an article is updated.
       If 
       you do not want to rely on the wp-cron, you can use wp-cli, so, instead of calling
       wp-cron via crontab – you should call it directly via wp `w3-total-cache pgcache_prime`
       and track the output which pages / sitemap positions are primed by script.
    3. Can you please clarify what happens if you clear the cache of the specific page
       and how it does not work?
       Thanks!
