But here is simple way out of this problem.

 

Important Note: Compressing, Minifying or Deferring Files may have adverse effect on functionality of website because of dependencies so first do following steps on your local server if everything looks to be working fine then you can update same files on Live servers. Just for safety & security purposes.

 

Here is example:

 
When you ‘Analyse’ your website on Google PageSpeed you get warning something like this:

 
Your page has 4 blocking script resources and 8 blocking CSS resources. This causes a delay in rendering your page.
None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

How to enable HTTP persistent connection or HTTP keep-alive for your website for faster page speed using .htaccess file

Mandar Apte Apple, Apple macOS, Open Source, Tutorials, WordPress Leave a comment

As Wikipedia explains:

 

HTTP persistent connection, also called HTTP keep-alive, or HTTP connection reuse, is the idea of using a single TCP connection to send and receive multiple HTTP requests/responses, as opposed to opening a new connection for every single request/response pair. The newer SPDY protocol uses the same idea and takes it further to allow multiple concurrent requests/responses to be multiplexed over a single connection.

 

Note: I assume you have adequate knowledge of handling your server & server settings & you are well versed in your field

 
You can put following code in your .htaceess file which is available in your root of your server’s html folder

How to disable WordPress Pingbacks & Trackbacks, One of the old Feature & Core Functionality of WordPress, Optimum Performance Tip

Mandar Apte Open Source, Tutorials, WordPress Leave a comment

Let’s Know, What is really Pingback is?

 
A pingback is a type of comment that’s created when you link to another blog post where pingbacks are enabled. The best way to think about pingbacks is as remote comments:

 

  1. Person A posts something on his blog.
  2. Person B posts on her own blog, linking to Person A’s post. This automatically sends a pingback to Person A when both have pingback enabled blogs.
  3. Person A’s blog receives the pingback, then automatically goes to Person B’s post to confirm that the pingback did, in fact, originate there.

 
Let’s Know, What is really Trackback is?

 
Trackbacks are a way to notify legacy blog systems that you’ve linked to them. If you link other WordPress blogs they’ll be notified automatically using pingbacks, no other action necessary.

 
Think of trackbacks as the equivalent of acknowledgements and references at the end of an academic paper or chapter in a text book.

 
To send a trackback, add the trackback URI from the other blog post to the Send Trackbacks module in your blog post before you publish it. A trackback URI from a WordPress blog will end with /trackback/.
