On the Dashboard for the last week or so I've been seeing very slow performance. With the help of the Query Monitor plugin I'm able to see that POST requests to api.wordpress.org are taking 5 seconds each. When that involves 4 or 5 requests, that's a long time. More details from Query Monitor are here - http://pastebin.com/jqnWTQZv
Has anyone else experienced this? What might be the cause?
