I've setup wordpress on AWS. I want to reduce as much network traffic as possible. What services/jobs do I need to disable in Wordpress?
WP_HTTP_BLOCK_EXTERNAL constant (
wp-config.php is good place to do this) would kill all outgoing network requests, other than those for hostnames, defined in
See source for details, doesn't seem to be documented in Codex.
If you want to see all network traffic from your site check out the Core Control plugin: http://wordpress.org/extend/plugins/core-control/ You can also use this to permit or shut down different requests and cron jobs.
Note, by defining WP_HTTP_BLOCK_EXTERNAL in your wp-config.php this blocks all external requests. If you want to enable WordPress update checks you will need to include api.wordpress.org in WP_ACCESSIBLE_HOSTS.
