Title: Server response speed issue Last modified: December 5, 2025 --- # Server response speed issue * Resolved [mkamel9089](https://wordpress.org/support/users/mkamel9089/) * (@mkamel9089) * [4 months, 1 week ago](https://wordpress.org/support/topic/server-response-speed-issue/) * Hello sir, I’m facing this problem right now, can you help me with it? * ( Median server response time was 1٬057 milliseconds. It should be less than the recommended 600 milliseconds threshold.) * ![](https://i0.wp.com/reluctant-lavender-seamie6yia-aoxe2a6xh2.edgeone.dev/Screenshot% 202025-12-05%20185321.png?ssl=1) Viewing 4 replies - 1 through 4 (of 4 total) * Plugin Support [Jen H.

In this case, WP Super Cache alone usually isn’t enough to fix this if something else is slow. * **Some recommendations for improvement:** - Update to a fast PHP version (8.1/8.2+) and consider dedicated (or different) hosting if TTFB stays >1000 ms on simple pages.​ - Disable heavy plugins, test with a default theme, and optimize the database to reduce slow queries.​ - Optimize your database with a reputable tool, or from your host’s panel, to cut down slow queries. * There is an extensive Optimization doc available here, if it helps: [https://developer.wordpress.org/advanced-administration/performance/optimization/](https://developer.wordpress.org/advanced-administration/performance/optimization/) * Let us know how it goes! * Thread Starter [mkamel9089](https://wordpress.org/support/users/mkamel9089/) * (@mkamel9089) * [4 months, 1 week ago](https://wordpress.org/support/topic/server-response-speed-issue/#post-18748131) * hello [@jenhooks](https://wordpress.org/support/users/jenhooks/) * I tried disabling the plugins one by one to identify the cause of the issue. The problem was finally resolved after deactivating the **WP Super Cache** plugin. * After that, the performance improved and the **median server response time became 354 milliseconds**, which is below the recommended threshold of 600 ms. * Could you please let me know what steps are required to continue using the plugin without causing this issue again? Your guidance would be appreciated. * ![](https://i0.wp.com/tall-turquoise-gbjdcexwwn-gb9rofqegd.edgeone.dev/Screenshot% 202025-12-09%20080931.png?ssl=1) * Plugin Support [Animesh Gaurav (a11n)](https://wordpress.org/support/users/bizanimesh/) * (@bizanimesh) * [4 months ago](https://wordpress.org/support/topic/server-response-speed-issue/#post-18753178) * Hey [@mkamel9089](https://wordpress.org/support/users/mkamel9089/) – Could you please activate the WP Super Cache plugin again, then go to _Settings » WP Super Cache » Advanced_ and enable _Expert mode_? After enabling it, let us know if you notice any changes. * Also, in our last reply, we recommended updating to a faster PHP version (8.1/ 8.2+) and optimizing your database. I wanted to check whether you had a chance to try those suggestions as well? * Plugin Support [Tamirat B.
