How to debug slow response

    Today, after no apparent changes, my page views, admin operations, and generally all navigation in my blog (xpxboston.com) takes 7-10 seconds to load the page. This happens not just to me, but for all users. I don’t believe that it is the web server or MySQL, since I have custom code on the same site, using custom tables in the blogs database, that respond almost immediately. I have no plug’ins that go to off-site services as far as I know, though it almost seems as though it might be going off-site and then timing out. Anyway, how does one go about debugging this type of issue? Any advise would be appreciated.
    Thanks, Rich

    Test your IP at ultrahosting with ping, traceroute, etc: Traceroute, Ping, Domain Name Server (DNS) Lookup, WHOIS

    Thanks, I checked that. Pings and traces real fast. In fact, if you go to xpxboston.com/events (a php file on the same server with a query to the same mySQL database) it returns very quickly, but going to the WP site, xpxboston.com, it takes a lot longer.

    Must be plugins or javascript. You’ve got at least one instance of two identical scripts running in the header.

    Thanks for looking. I am not sure what is causing the duplicate javascript – I will have to look for that. However, I think I have the slow response time narrowed down to a plug-in called Social Access Control, and only on pages that have some sort of Post display (the Page display fast). When I deactivate Social Access Control, the response time is normal again. I will see if the Plug-in developer has any idea. I am going to mark this as resolved as it does not appear to be a core WP issue.

    Did you resolve this? Same problem. My host said it’s causing hundreds of sql queries before page load.
