Comment:

 Re-opening because of my experience with this issue.

 In a nutshell, I migrated a WordPress site (two, actually) to a different
 server, and initial site loads were taking 18+ seconds, while subsequent
 loads were < 1 second.  After a while troubleshooting, I enabled WP_DEBUG
 and saw this warning ("doing_wp_cron" had a value in the query string).
 Installing php5-curl resolved it, and now initial site loads are < 2
 seconds.

 For more information, part of my troubleshooting was disabling all plug-
 ins, and changing the theme to Twenty Ten, and still the load issues
 persisted.

 Once I came across this thread, I recalled that one of my installed
 plugins depends on php5-curl for functionality.  Perhaps there is a coding
 issue with that plugin, since I was still impacted by this after disabling
 the plugin, but it nonetheless underlines the fact that this is an
 important issue with real performance side effects.

 Site loads were 18+ seconds any time Apache was restarted, or the site
 hadn't been accessed in the previous ~30 seconds.  This is on WordPress
 3.6.1.
