Since updating to Wordpress 3.5 I've had my updates of pages and posts become excessively slow. I've been timing them and they take 40-80 seconds to update.

I've spent the last 2 hours reading and trying everything I can find in the Wordpress.org forums yet nothing works.

I use maxcdn and CloudFlare for the frontside but the backside is unbearable.

I am on a MU install using 3.5.2 and I have disabled and tested each plugin. Seems to be a Wordpress issue and I'm looking for a workaround.

I'm on dual core VPS with 3GB of ram.

  • hey gabearnold, how far have you gone with that? Have you found where is the bottleneck? Is it your Server(Apache/Nginx), your database, your application? what do the logs say?

  • It's apache. I am looking in the logs and TOP in MySQL and nothing glaring stands out...

  • To get sure the problem is not with your MYSQL you can run SHOW PROCESSLIST; when trying to insert a new post and see if there is any query taking longer then it should. Or rather, turn on your slow_query_log... ;-)

  • It's not taking quite as long as you're reporting, but I've seen a definite (albeit anecdotal) slowness on the backend since updating as well.

There's a plugin called Debug Bar which you can find at http://wordpress.org/plugins/debug-bar/ Don't leave this enabled in production! But it will tattle on slow MySQL queries.

You might also wish to try using WP Clean Up. http://wordpress.org/plugins/wp-clean-up/ This flushes out stale entries in your database, and does a little bit of table reorg/optimization.


I had the same thing today. It turned out that WP Maintenance Mode plugin slowed down my website. After I deactivated the plugin, all was good again.

Maybe it helps someone.
