Update a WordPress post or page takes 60+ seconds

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.

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.
