I just now “Disabled Transport” link in for CURL under the external HTTP access. Now everything is flying. Awesome!!
Having the same problem: slow dashboard.
I thought the RSS Error might be the culprit. Searched: “WP HTTP Error: Resolving timed out after 10520 milliseconds,” which took me here:
https://wordpress.org/support/topic/dashboard-issues-rss-error-wp-http-error-name-lookup-timed-out, where member ashiado says he solved the problem.
ashiado: Finally SOLVED by installing the Core Control plugin and then following the directions here: http://wordpress.org/support/topic/231500?replies=12#post-1168609
Now go to this page and look for CarltonBale for directions.
My dashboard is really fast after I get into it. Everything is fast except the Themes.
Regards.
