In this article, I will share my personal experience regarding this blog performance and nightmares of disabling website everyday because of CPU Utilization. I tried all my best however I was unable to figure out the cause of high CPU Usage by wordPress. I tried many articles on Google and at last I found some pointers and able to escape from this problem.
This article is specific to my problem only, However I am sure it will help many others also.
I started with ways, which will less impact my blog and will take less time.
1. Disable WordPress Cron Job
This was my first step, disabling cron Job. In most of cases we are not using this feature. Mostly it is used when you schedule some article to publish on some day or time. To disable it, Open “wp-config.php” file and add below line at top of page.
What if I need this cron job ?
You can easily create a cron Job anytime, by following below process.
a. Log into your cPanel.
b. In the Advanced section, click Cron jobs.
c. Under Add New Cron Job, select the time interval. It is recommended not to add time interval less than 15 minutes.
d. Set the cron command to the following, replacing yourwebsite.com with your actual domain name:
wget -q -O – http://yourwebsite.com/wp-cron.php?doing_wp_cron >/dev/null 2>&1
The above command tells the Linux server to run wp-cron via wget, which will trigger the wp-cron.php script to do it’s job on your schedule instead of on each page view. This will lessen the amount of processes on the server.
e. Click Add New Cron Job to set the cron.
2. Disable Plugins
Now, Here comes actual reason for WordPress blog high CPU usage. I had many plugins and started to disable one by one.
