Troubleshoot delay on web page load relating to OpenSSL xmlrpc delay


Job Description

I have a network of web-sites with significant page delays resulting from loading xmlrpc.php in wordpress. Each page load pauses for 1-3 seconds, apparently while processing xmlrpc.php through the OpenSSL interface. See gtmetrix report, attached.
