Title: [Plugin: WP Super Cache] wp super cache still hitting php Last modified: August 20, 2016 --- # [Plugin: WP Super Cache] wp super cache still hitting php * [CldSwm](https://wordpress.org/support/users/cldswm/) * (@cldswm) * [14 years, 2 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-wp-super-cache-still-hitting-php/) * I’m confused. I have super cache running in advanced mod_rewrite mode with all of the recommended settings. when i view the source I’m seeing the correct “dynamic page generated by super cache and compress =gzip stuff”. * however when I’m monitor the server I’m still seeing a lot of cpu activity with a lot of php processes: * example: /usr/bin/php /home/****/public_html/index.php * I thought the whole thing with super cache and mod_rewrite was that it completely avoided evening loading php. Is this an incorrect assumption on my part? If it is any suggestions on how to further cut down on the cpu usage by those wordpress index files? * Thanks!! * [http://wordpress.org/extend/plugins/wp-super-cache/](http://wordpress.org/extend/plugins/wp-super-cache/) Viewing 2 replies - 1 through 2 (of 2 total) * Thread Starter [CldSwm](https://wordpress.org/support/users/cldswm/) * (@cldswm) * [14 years, 2 months ago](https://wordpress.org/support/topic/plugin-wp-super-cache-wp-super-cache-still-hitting-php/#post-2666529) * i enabled debugging and saw this on ever post. * 18:43:57 /2012/04/03/mr-kate-days-of-ore-jewelry-lookbook/?cf_action=sync_comments& post_id=23910 Output buffer callback 18:43:57 /2012/04/03/mr-kate-days-of-ore- jewelry-lookbook/?cf_action=sync_comments&post_id=23910 No closing html tag.

In disqus you can disable sync which basically means your comments only go to the disqus server and not back to your wordpress installation. * I’m no longer getting those errors. CPU is still pretty high, but now the cache is being recreated so we’ll see if this helps…. * Plugin Author [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [14 years, 1 month ago](https://wordpress.org/support/topic/plugin-wp-super-cache-wp-super-cache-still-hitting-php/#post-2666815) * I think you’re right about Disqus. Unfortunately it syncs quite often..
