Been trying to figure out why the WordPress blog I’m running is so often slow to respond to the initial HTTP request. Eager for pointers about what other strategies I should try to (a) understand what’s wrong and (b) fix what’s wrong.
Monitoring the home page for the last week from an external service shows average response of just over 3 seconds, and repeated spikes of up to 7-8 seconds. This is for first response, not measuring full page load. (None of the pages are super heavy: once the server responds, the page pops in.)
See graph for Thursday Jan 28 2010 here. Top graph is the WP blog. Bottom graph is a flat file site running on the same hosting service, for comparison.

Not a high traffic site: information about an industrial adhesives/coatings company.
