There are numerous factors for the slow WordPress website/blogs and their admin panel/dashboard. The main cause of slow loading & slow processing is a huge number of plugins, Images, some JS files we used on the website and the server response time

1. Delete Unused Themes From the website
2. Deactivate Unused Plugin and delete from the website
3. Avoid Using the High CPU Uses Plugins
4. Update your PHP version of the Hosting
5. Configure Cache WP Rocket or W3 Total Cache
6. Cleaning the database, means removing the extra tables.
7. Identify the Sources of high CPU
8. Avoid EIG Hosting
9. Configure WP Disable
10. Host website with the best Hosting provider like Siteground
11. Limit & Block Spammy Crawlers

First of all, we need to remove all the unwanted or unused plugins from the website, then we need to check which plugin is having the high CPU uses, so that we can remove or can find the better option instead of that plugins.

Then we need to optimize each image, CSS & JS files. So, let’s come with me will guide you how you can identify images, CSS files, & JS files that need to optimize along with the plugins which have high CPU uses.

To check the images, CSS file, JS files & high CPU uses Plugins you can check your website at the GTmetrix, and check the each tabs one by one: PageSpeed, Yslow, Waterfall, Timings etc…

Now, you need to follow all the given recommendations, like optimizing the Images, CSS, JS etc…

Click each tab one by one and follow the instructions, you can download the compressed file from there as well & can replace with the older files.

(Please note you must take the backup of each file & folder before making any changes or I would suggest you rather than deleting the old files, just rename it and upload the compressed one)

To check the high CPU uses/Slowest plugin, you can find at the Waterfall tab, which regularly appears multiple times in your Waterfall, Page Speed, and YSlow report when you hover over your URL.

You can also check the Timings tab in the GTmetrix …

1. Delete Unused Themes From the website

Remove extra theme from this section, as while installing the WordPress by default 3 themes get installed on the website, just check which theme is active & remove all the extra themes other than the active. or you can delete the extra theme folder from the Cpanel in wp-content-> theme

2. Deactivate Unused Plugin and delete from the website

To deactivate & delete the extra plugins you need to go plugins menu and check which plugins are not in use just deactivate & delete that.

3. Avoid Using the High CPU Uses Plugins

Some of the common high CPU uses plugins are page builders, Chat, Multiple Gallery, Facebook Comment, Yelp Comments, related post, statistic sitemap, calendar, and many more plugins that run ongoing scans or show in processes. You can check on the GTmetrix Waterfall tabs which appear multiple times. Below I’ve mentioned 30 plugins name you should avoid using:

• Fuzzy SEO Booster
• Google XML Sitemaps
• Slimstat Analytics
• Broken link checker
• Contextual Related Posts
• Option Tree
• Sumo Me
• Next GEN Gallery
• Better WordPress Google XML Sitemaps
• WP Power Stats

• WP-Post Views
• Jetpack
• WP Cloaker
• AdSense Click Fraud Monitoring
• Digi Auto Links
• WordPress Popular Posts
• Vault Press
• WordPress Related Posts
• Yuzo Related Posts

4. Update your PHP version of the Hosting

The latest PHP version is PHP 7.2, but I would recommend you to use the PHP7.0 version as some of the Plugins & theme don’t compatible with the 7.2 version or even PHP 7.0. So before upgrading your PHP version please check each plugins version compatibility using the PHP Compatibility Checker plugin, and to know your website PHP version use this plugin Display PHP Version plugin.

5. Configure Cache WP Rocket or W3 Total Cache

WP Rocket is one of the best Cache plugins, as this is the premium plugin of Worth rupees $39 and with this amount, it is not at all bad choice. If you don’t want to give load on your pocket just go for the W3 total cache Plugins. These plugins will help you to improve your website speed as well as the search engine result page ranking. More than 10X times your website speed will improve.

Note: If you are using the W3 total cache Plugins you must disable the object cache in the General settings of the plugins.

6. Cleaning the database, means removing the extra tables.

When we install some plugins new tables in the database get created, and even after deactivating/deleting the plugins some table with the data remain stored there. So, we need to remove these from the database as well.

Also, some temporary folder, trash folder and post updates stored in our database, that also, need to remove. You can do this by the WP Rocket plugins for the database settings.

You can also use the WP-Optimize Plugin

7. Identify the Sources of high CPU

To identify the high CPU uses you can check the Awstats at your Cpanel under the Metrics section. Awstats will help you to identify the High bandwidth Crawlers, IP addresses, Download files, images, Total bandwidth usage (for monitoring).

Or you can use this plugin WP Server Stats plugin, this plugin will help you to monitor your website & its core level. It will give you almost all the important server stats like CPU usage, Allocated memory & Realtime memory & etc. So, that you can easily identify the what wrong going on your website.

8. Avoid EIG Hosting

First of all let me tell you about the “What is EIG” EIG hosting provider, for the cost cutting they put a number of users at the same server, which impacts the server response time and the website speed as well. You can check 83 hosting company who owns EIG:

9. Configure WP Disable

To disable the some of the settings in the WordPress, you need to install the plugin WP Disable which will help you to identify the setting by which the site is loading slow or disabling the unwanted process.

You can set the WP Disable settings:

• Check & disable which are you are not using.
• Host your Google Analytics tracking code locally in the right side of settings
• Emojis, Google Maps, and Gravatarstake a long time to load

• Pingbacks and trackbacks aren’t usually worth the extra resources
• Scheduling spam deletion is a good idea
• Disable everything in the “tags” tab since they’re all unnecessary
• Set post revisions to 3-5 so you have backups, but you don’t need hundreds
