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.
