Title: 3.8 extremely slow Last modified: August 21, 2016 --- # 3.8 extremely slow * [dannymh](https://wordpress.org/support/users/dannymh/) * (@dannymh) * [12 years, 6 months ago](https://wordpress.org/support/topic/38-extremely-slow/) * Ever since the upgrade to 3.8 my site has been running extremely slowly. Some pages take upwards of 20 seconds to load with some hitting the 50 second mark. Prior to 3.8 pages were loading in 5 seconds max. * I added caching so the cached pages load at a reasonable speed however uncached pages are just unusable and I am losing ranking and visitors due to this. * before going through a risky downgrade I wanted to see if anyone had any thoughts. * What i have tried – Disabled all plugins – Changed theme to default theme – reset the plugins folder – added caching – disabled gravatars * I cant for the life of me figure out what may be causing the slow down here. Any help would be appreciated. I can provide any log needed, this is a VDS so I have full access to provide what may be needed. * Last option will be downgrading back to 2.71 * URL is [http://www.silvertails.net](http://www.silvertails.net) (front page will load quickly because of caching so you will need to click through to direct articles/ posts to see how slow it gets) * Dan Viewing 15 replies - 1 through 15 (of 36 total) 1 [2](https://wordpress.org/support/topic/38-extremely-slow/page/2/?output_format=md) [3](https://wordpress.org/support/topic/38-extremely-slow/page/3/?output_format=md) [→](https://wordpress.org/support/topic/38-extremely-slow/page/2/?output_format=md) * [kmessinger](https://wordpress.org/support/users/kmessinger/) * (@kmessinger) * [12 years, 6 months ago](https://wordpress.org/support/topic/38-extremely-slow/#post-4527930) * [http://www.phpcoder.org](http://www.phpcoder.org) shows registration expired. * Thread Starter [dannymh](https://wordpress.org/support/users/dannymh/) * (@dannymh) * [12 years, 6 months ago](https://wordpress.org/support/topic/38-extremely-slow/#post-4527953) * ???? * Thats a different and older domain. * The site is in the post above [http://www.silvertails.net](http://www.silvertails.net) * [kmessinger](https://wordpress.org/support/users/kmessinger/) * (@kmessinger) * [12 years, 6 months ago](https://wordpress.org/support/topic/38-extremely-slow/#post-4527955) * Sorry, that is the domain listed on your profile. * Thread Starter [dannymh](https://wordpress.org/support/users/dannymh/) * (@dannymh) * [12 years, 6 months ago](https://wordpress.org/support/topic/38-extremely-slow/#post-4527957) * no worries, one of many of my sites. * Silvertails is the current one experiencing the issue * [kmessinger](https://wordpress.org/support/users/kmessinger/) * (@kmessinger) * [12 years, 6 months ago](https://wordpress.org/support/topic/38-extremely-slow/#post-4527959) * WP 3.8 would not make the site slower.
