Performance

• PHP Performance Keep 10 revisions per post Keeps the last 10 revisions of each post and page instead of every one, so the database doesn’t fill up with old versions.
• PHP Performance Slow down the Heartbeat API While the admin is open, WordPress checks in with the server every 15 to 60 seconds. Once a minute is enough for post locks and login checks, and saves server work.
• PHP Performance Empty the trash after 7 days Deletes posts, pages and comments for good after 7 days in the trash, instead of 30.
• PHP Performance No pingbacks to your own posts When you link to one of your own posts, WordPress sends it a pingback, which shows up as a comment. This stops that.
• PHP Performance Load Dashicons for logged-in users only The Dashicons icon font is loaded on the public site for the admin bar. Visitors who aren’t logged in don’t need it.
• PHP Clean up the head Remove the emoji script and styles Stops WordPress from loading its emoji script and styles on every page. Every current browser shows emoji on its own.
• PHP Clean up the head Stop loading jQuery Migrate jQuery Migrate helps very old jQuery code run. Most sites don’t need it on the public pages; the admin keeps it.
