CPU usage issues are common on WordPress websites. They become more common when you are using shared resources or a hosting plan that does not have as many resources. However, CPU usage can also occur in a good hosting plan. When this happens, it slows down your website drastically because there are no resources to deliver content to your site.
CPU usage issues can not only lead you to bad user experience but also quickly impact your website ranking.
In this article, we are going to learn how to minimize CPU usage in WordPress. All of the tips we will share are straightforward and easy to follow. However, if you can still use a developer who can do it for you. So, no moredelay, let's start.
1. Get rid of unnecessary plugins 
The plugins offer excellent value - price when it comes to adding functionality to the website. Any website would require a set of plugins to function properly. However, it is clear that as users we install plugins that we do not need. Sometimes we install plugins for testing and then forget to remove them. In other scenarios, some functionality of the plugin overlaps to some extent. Either way, it is always a good idea to remove these plugins and reduce CPU usage.
Note: Always uninstall plugins according to official guidelines. If you are unsure, always refer to the documentation saying that removing the plug the wrong way around may affect the functionality of the site of myundesirable nière.
2. Configure WP Disable
Another nifty way to reduce CPU usage is to use WP Disable . WP Disable is a plugin that allows you to disable WordPress settings that consume unnecessary CPU cycles. For example, you can turn off embeds, emoticons, and more. Besides, it also helps you reduce HTTP requests which can further improve website performance. Once you have installed the plugin, you will be given the option to do so with an easy to use interface.
It also provides dashboard stats so you can monitor important things right off the bat. We recommend that you turn off items that you simply don't need. Remember that you can always reactivate them by activating the option. Also, if you are not sure about an option and whatit does, you better ignore it.
3. Image optimization
Another most important bottleneck that modern websites go through a poor image optimization . Let's take an example to better understand. When a page loads, it loads different elements including images. Along with images, their metadata is also loaded. However, metadata doesn't help (in some cases). So you can remove metadata from images and make the page easier for the processor to process.

4. Configure WordPress crawling rules
Believe it or not, your website is crawled by lots of botsexploration. But not all crawlers are useful. Some are there to scrape your data for some other use. When a robot crawls a site, it uses precious CPU cycles. To make sure that doesn't happen, you can easily block them and only let the most important crawl your website.
You can use the "crawl speed limit rules " feature in Wordfence to make sure a useful bot crawls. Also, you can change the crawler settings as long as your website is not slow due to unnecessary CPU usage. You can also block the IP address if you suspect that someone is continually hammering your servers for no reason. It will improve the experience of legitimate visitors and improve the performance of the processor in each scenario.
5. Limit the exploration of Google+ Bing
The moPopular searchers exploring your website are essential. However, they are resource intensive, especially Google's crawler. The good news is, you can limit the site crawl rate for Google and Bing. By doing this, you don 't affect your Google ranking. According to Google, you can customize the crawling speed according to your preferences. For example, a news website should always have a higher crawl rate than a site that posts once per day.
If so, you need to go to Google Search Console and search for "site settings ". There you can find the low crawl rate option. Bing also offers similar crawl speed control. You can do this by going to Bing Tools for Webmasters and then editing it in " Exploration Control Settings ”.
6. Database cleaning
Another good way to improve processor performance is to clean your database. If a database is full of unnecessary information, processing a simple query takes more CPU time. Now imagine how much of an impact learning about database can have if your website requires multiple queries per second.
With regular queries, your database stores a lot of data that is not necessary for the proper functioning of the website. Some of the examples include post revisions, trash cans, transients, etc. In addition, plugin data is stored even after uninstalling a plugin. This can lead to a bloated database.
The best approach is to use optimization plugins such as WP-Optimize and WP Rocket regularly. You can use both pluginss to automate cleaning.

Some of the plugins that can slow down your website or consume precious CPU cycle are Jetpack, SumoMe, Visual Composer, etc. To know the impact of a plugin on your site, you can install it and then go to GTmetrix to check its impact on the site. If this is too much, it is better to avoid it and find an alternative.
If you are unsure about CPU intensive plugins, you can use free hosting to try the plugins. There are various hosting providers like 000webhost which offer free hosting for beginners. You can also choose to use localhost and check CPU usage. If all looks good, then you can install the plugin on your live website.
