With one of my Wordpress sites, I'm noticing it takes around 15 seconds to log in. That is way too long and I'm trying to find what is causing it. Is there something I can use to diagnose all the calls it's making during log in?
I've tried disabling plugins but don't see a difference.
You could try Google Chrome's Audit in Developer Tools. Compare the login to the previous page load and see what files (images, css, js) are different. It may also (IMO most likely) be a server side database issue.
I will check if it has anything to do with css, javascript, etc but I really think it's something with either plugins or theme code that's causing a lag time while trying to perform a filter or action. But I've tried disabling plugins and doesn't seem to be making a difference.
