Trying to do anything in our WP Admin site is horrendously slow since the 4.5.2 update. Switching from post to dashboard used to take 1-5 seconds now takes 20 to 30. I've disabled all plugins, and still have the problem. Using Genesis with Foodie Pro theme (Just noticed that Foodie Pro is version 2.0.5, but i see in 2.1.8 is the latest - i'll try to update and see what happens).

Site users do not seem to have this issue. It is only the wp-admin site that seems to be really slow.

I saw this article (https://wordpress.org/support/topic/upgrade-to-wp-452-blocks-all-admin-access?replies=2) so I think some others are having the same issue.

One more possible reason is Search engine crawling
search engine crawl make website slow if your website hv large numberof pages

Same here, it been extremely slow for me.

Me too. Seems to be linked to WooCommerce and WooCommerce Subscriptions for me too.

Painfully slow front and is affecting the front end too - but probably because I'm logged in as admin. Loads ok in Incognito browser window. Just the admin side then.

I've just upgraded to 4.5.3 and no change. Still very slow, 80 seconds. Was longer previously.
