As developer of sites in WordPress in Entrebits we have the healthy custom to stopthe functionHeartbeat de WordPress, this supposes in many occasions a drastic reduction of the execution of admin-ajax.php that is not more than the file than executes the administrator of WordPress, also known as backend. Empezemos to know more on the Heartbeat and its problematic one.

What is the Heartbeat?

The Heartbeat was introduced in WP 3,6 and its main function is to block the edition of the content that is being published then by a user and to provide in real time information through writing-desk. It is really useful if there are several people working in a same website. We suppose that we have a store online and are two managers, the manager issues the order to increase stock of a product, they both enter store managers Woocommerce and modify simultaneously, this can create conflicts, since the information of the last manager who enter will sobrescribirá the one of first. The blockade imagines as a together padlock the entrance, page or product in case you have Woocommerce to publish.

Other CMS as Joomla! they have the option of blockade but in this case more individual is something, WordPress introduces a blockade temporary, every 15 seconds it verifies if there is some edition content and to whom is attributed it, when it stops publishing the blockade only disappears. Generating a request POST similar to the one of the following graph - in this case every 60 seconds. This causes that hostings is consumed resources being him equivalent in many to a visit every 60 seconds. In the graph we see since there is a single visit to the site, in green, the rest are all requests of Heartbeat.

By all means this consumes RAM, CPU and executions of the servant, if you have many visits, perhaps the sum of the Heartbeart de WordPress plus the views and the tracking of robots shoots your account of lodging, for that reason he is recommendable to be preparations, to optimize the execution of Heartbeat, we go to the grain.

Some hostings as Siteground offers the possibility to you of knowing that script siendos is executed. This information is very useful to know if the control of the Heartbeat is working. In this account the executions of index.php and admin-ajax.php were similar, after controlling Heartbeat the executions of admin-ajax are practically testimonial. This saves a great amount of resources and executions to the servant.

Optimizing Heartbeat through file functions.php of your group

To optimize Heartbeat in WordPress is very simple and is question of some minutes. You can, according to your knowledge to do it of two ways: through a code in funtions.php or plugin that will add that same code by itself.

In order to optimize through functions.php we must locate the folder of our group that must be located inpublic_html/wp-content/themes/tuplantilla. For it accedes you can use a client FTP as Filezilla or if you have CPANEL or FTPWeb, sailing through file manager. If it beams thus, you will arrive at the set of archives of your group where we found functions.php

We recommended to you to make a backup copy of your file functions.php before realising any change. If something left bad, you will only have to erase the modified one and to return to load the original one. In order to make a copy it unloads the file in your computer. In order to publish it if these in CPANEL pudes to publish doing it click in the right button and Edit. If these in FTP you will have to unload the file, to publish it with a publisher of code as Notepad ++ and to return it to raise the servant. Once we know we have located the file and we know to publish it, we happen to add the code. In order to deactivate it you will have to add the following code:

add_action (€˜init€™, €˜stop_heartbeat€™, 1); function stop_heartbeat () \ {wp_deregister_script (€˜heartbeat€™); }

This will stop Heartbeat completely. If your hosting is SiteGround you can verify as the executions of admin-ajax.php will collapse if you are not working with the administrator. If you are in another one hosting we invited to you that you see the statistics of use of the CPU and the memory.

Optimizing Heartbeat throughplugin Heartbeat Control

Before home, very important to do a thing or the other. If you add the active code functions.php and Heartbeat Control you run the risk of which your group fails. Anyway if you receive some coarse error with deactivating plugin, since this plugin when modifying a group file never is going to you to prevent to accede to the WP administrator After this recommendation we begin!

You can go to repositorio WP official and unload plugin to you or directly to ask for it from the administrator of WordPress. You will see that it has been two years without updating itself, there is no problem, it is a so stable characteristic of WordPress that it has really not required of updates. We looked for it and we click in Installing Now.

After installing we activated it and we will find the Control Panel in Adjustments > Heartbeat Control. Its configuration is very simple. In one first stage we will select if we want to deactivate it of the Writing-desk - the Heartbeat works every 60 seconds here, of the Edition of Post - every 15 seconds or of both. If the site really goes to be managed by a single person or whom are not going to agree, the ideal is to retire it totally.

In one second phase if you wish it, leaving it activates some of the previous options, you can indicate each how long will pass the Heartbeat, for example in the Edition of Post we can happen of each 15 to 60 seconds with the following configuration:

After Keeping Changes we can verify since has been added new line funcions.php automatically.

Up to here the control of Heartbeat in WordPress, a healthy optimization, as long as their function is not necessary that it will reduce the consumption of resources of our servant reserving them for our visits. If you have any doubt you can put to you with our Maintenance service for WordPress in touch.
