Title: Possible Plugin Improvement Last modified: August 21, 2016 --- # Possible Plugin Improvement * Resolved [awhig](https://wordpress.org/support/users/awhig/) * (@awhig) * [12 years, 7 months ago](https://wordpress.org/support/topic/possible-plugin-improvement/) * Hi, * I use W3 Total Cache, as my caching plugin. I specifically use the Object Cache, to improve the speed of my WP install. * I was doing some testing, to see if I could speed up my site, and saw that many queries were being repeated over and over against my DB. I investigated and saw that data was being stored in the object cache, but found that the object cache was being flushed periodically, about once every 5 minutes. * I tracked the cause being this plugin. It stores the last run time in the wp options table, using update_option method. * When an option is updated, this causes the Object Cache to be flushed, as the options are also stored in the object cache. * This then causes all of the stored data to be flushed and all of the queries have to be re-executed. * I’m pretty sure most persistent object cache’s also flush when the options are ever updated (Super Cache, etc). This increases load on the DB and slows down performance for WP. * Please consider using another mechanism to store the last run time of the plugin. I believe the options data should be pretty much static. It shouldn’t be updated every 5 minutes. It should only be updated whenever the admin makes a material change to WP or plugin settings, which does not happen in the normal execution of the site. * I’m not sure where to store this info though. Because I’m using a persistent object cache, I can make the change in my own local copy to store the last run time in the object cache (wp_cache_set() ), instead of the update_option(). This would work in my case, but would not work for everyone, as they may not be using a persistent cache. * Thanks, Rich * [https://wordpress.org/plugins/wp-missed-schedule/](https://wordpress.org/plugins/wp-missed-schedule/) Viewing 4 replies - 1 through 4 (of 4 total) * Plugin Contributor [slangji](https://wordpress.org/support/users/slangji/) * (@slangji) * [12 years, 7 months ago](https://wordpress.org/support/topic/possible-plugin-improvement/#post-4701051) * _so?_ * **1st:** if you need other times of checking consider [WP MIssed Schedule Gold](http://wordpress.org/support/topic/special-gold-edition-version-installation-guide) download [here](http://downloads.wordpress.org/plugin/wp-missed-schedule.2013.1231.2013.Special-Gold-Edition.zip) * **2nd:** if you have your own code (or alternate) solution, i am happy to analize it and implement on developmental version … send [here](http://slangji.wordpress.com/contact/)** please note that this code was compatible with WordPress 2.5+ to 3.9+** * **3rd:** configure W3 Total Cache or WP Super Cache to exclude from object caching WP MIssed Schedule * **4th:** use alternative Object Caching method [Tribe Object Cache](http://wordpress.org/plugins/tribe-object-cache/) for example … * > This issue was inserted as **Ticket #5333092** on to [Todo List](http://wordpress.org/extend/plugins/wp-missed-schedule/changelog/) > for Future Development. * Thanks to [awhig](http://wordpress.org/support/profile/awhig) and all others users was send me same solution via [Contact](http://slangji.wordpress.com/contact/) form … * If are satisfied of this plugin, please, consider one small [Donation](http://slangji.wordpress.com/donate/) for my free work. 🙂 * **P.S.** Remember that your implementation request is not planned for free plugin but for pay plugin or donation users: read changelog [here](http://wordpress.org/plugins/wp-missed-schedule/changelog/) 😉 * Plugin Contributor [slangji](https://wordpress.org/support/users/slangji/) * (@slangji) * [12 years, 7 months ago](https://wordpress.org/support/topic/possible-plugin-improvement/#post-4701184) * > I was doing some testing, to see if I could speed up my site, and saw that > many queries were being repeated over and over against my DB.
