I have a test wordpress intallation on localhost and recently I noticed the administration pages load very slow.
Everytime I’m connected to the internet and open the /wp-admin pages it takes 14-15 seconds to load. This does not happen in the front end.
Is there any way to get info about all the http requests that are being made in the page, just like getting the # of queries (get_num_queries)?
[EDIT: New Answer] After OP clarification, here is the changed answer:
You can install xDebug and enable profiler in that. Here is the step-by-step tutorial on how to do that: http://codex.wordpress.org/Testing_WordPress_Performance
This will tell you how much time spent in what part of code.
Old Answer:
I advise you to install Fiddler and get all the HTTP requests made, their responses and time taken.
