How to Fixed WordPress Cpanel Physical Memory Usage and I/O Usage frequently maxed 2019 Solutions
Memory Usage and I/O Usage for my Wordpress based website is constantly being maxed. Memory Usage will typically spike when I publish a new post, or edit a newly published post, and this causes the website to crash and return a 503 error.
This only started happening when my website was moved from Web Economy (Linux) hosting to cPanel Deluxe (Linux) 2 weeks ago, which I had paid GoDaddy to perform themselves. Ever since, crashing has been a constant issue.
I was told by WP Premium Support that this could be caused by high traffic to the website, which is apparently mostly spam? When I go to cPanel > Bandwidth, it says the HTTP usage is currently at 74.46 GB for January 2018. I was also told that part of this could be a high amount of views on the website’s forums (again, spam?). The website and the forums are on separate databases.
I was also told that the WP-Smush plugin, which I thought was an effective plugin to optimize images, was problematic because it creates several images of different sizes per image, maxing the website’s resources?
I have tried everything. Contacting GoDaddy web hosting support. Upgrading my cPanel Deluxe account to cPanel Deluxe 2. Paying for WordPress Premium Support. Looking at similar problems people have reported in the past. Disabling all plugins and trying to identify a culprit. None of this has worked, and I don’t know what else to do.
