 * Hello friend
 * I can see in the last version show a option “Use caching of translation. Only
   effective if any persistent object cache is installed.”
 * But how can I verify is really installed and this option really is working?
 * Another question:
 * no have conflict with another cache plugins? I am using Cachify

 * WPPP uses the WordPress object cache for caching. So you need to have any persistend
   object cache installed to see any speed improvements, e.g. EM Object Cache, APC
   Object Cache or other caching plugins, which contain an object Cache like W3 
   Total Cache.
    Cachify is a page cache only which doesn’t implement an object 
   cache.
 * You can verify if an object cache is installed by looking for _object-cache.php_
   in _wp-content_.
 * As WPPP uses the Default WP-Cache-API it doesn’t conflict with any other caching
   plugins.
 * Object cache plugins shouldn’t cause conflicts with Cachify. Cachify only serves
   front end pages to not logged in users from cache. So installing a cache like
   EM Object Cache and activating WPPP caching would improve performance for logged
   in users and backend.

 * By the way: I’m working towards version 1.0 which will include a simplyfied Interface
   similar to your previous Suggestion for which I try to implemet some kind of 
   auto detection of optimal Settings.

 * Ok, thanks for your assistance
 * I testing in the past some Objects caching and no working fine in my hosting,
   but I will test EM Object Cache
 * I think the auto-detection settings is really a great idea

 * I am testing EM Object Cache plugin in my website running very slow…
 * Do you think can works fine with Tribe cache or APC cache and WPPP?

 * Which object cache is best depends on your hosting environment and if any advanced
   caching options are available. For APC or similar ro work APC has to be installed
   on your host.
 * Most object caches offer some simple methods like DB cache or file cache which
   should be available on most Hosting evironments. But the performance of these
   might not be very good.
