2. Post Revision

The best CMS platform is considered for WordPress. WordPress is the best platform in order to keep an eye on drafts, blog post changes, and revisions. You can easily go back and regain the information that you have been deleted from the post.

This is possible because post revision is stored by WordPress. You can easily load up the previous version of the post or undo the changes.

The temporary version of the draft post will be autosave by WordPress. This will happens to all drafts and posts.

Every 60 seconds, the autosave will be stored in WordPress. Thus sequential order will be created of your edits. While creating or publishing the posts, these post revisions might be more helpful. At a time such a post can take a lot of space in a database which will ultimately result in the slow down of your server.

It is good to delete manually the older version of posts that are not in use. Plus you can add some parameters which will delete the post after the expiry date. These are accessible from the post editor.

The following code can be added to the wp-config.php file of your website to cap the total number of revisions.

define( ‘WP_POST_REVISIONS’, 10 )

10 is the actual total number of posts that you would restrict. By adding this code, no more than 10 posts will be created. That clearly means once 10 numbers crossed, automatically older post will be removed.

By phpMyAdmin, you can delete the existing post that is not in use, or you can do it by integrating the WordPress plugin. In this post, we will learn about those plugins as well.

3. Expired Transients

Transients are a WordPress tool that will help you or a developer to store required information in your database for some period of time. This will optimize the performance of your website and the website which is connected to you. It can also optimize the server loads.

With social media plugins, the common type of transients is used. To keep share counts for posts up to date these transients are used by WordPress.

Every time you don’t need to take re-permission with social media site. This will make your website slow. Thus these transients will be helpful for speeding up the process.

It is not guaranteed that the transients will work perfectly every-time especially when you are installing a plugin or doing some modifications. Rather than waiting for it to get expire it is helpful to manage them.

The expired transient will not be delayed by WordPress and from your database, it is a good method to clean them out. Your website can be slow down due to the large wp_options table. So it is a better option to delete the expired transients.
