Opening multiple WordPress admin window for sites on a shared host results in high CPU usage.
I have a few sites that I am trying to grow on a shared host. I noticed that when I open admin windows for about five of the sites, the CPU maxes out.
I sometimes find the need to have WordPress admin windows open for several sites on the same host. For example, If I want to check the plugins that are installed to make sure I have all the plugins I want on all the sites. Another example would be to look at the settings for a particular plugin on one site and apply those to other sites.
There is a definite correlation between the number of open WordPress admin windows and CPU Usage. As soon as I open a couple of admin panels, the CPU usage as shown in my cPanel goes to 100 percent. There could be a number of factors influencing this:
- The configuration of your hosting, especially CPU and Ram provided by your hosting company.
- The plugins that are active on the WordPress sites.
- As soon as traffic increases, I will outgrow my current hosting plan
- I don’t want to add any more sites to this shared hosting (I was not planning to)
- I have to look at caching. I’m not sure if that will reduce CPU load or not.
- I need to make a note to close the admin windows when I’m done with them.
- setting up WordPress on an IP until you transfer the domain
- WP Super Cache for WordPress was not working on a shared host.
- Using Cloudflare with Westhost WordPress sites
- WordPress – Brute force attacks stopped with the wps-hide-login plugin
- This site was being attacked
- Migration from Frontpage to Expression Web on Linux/Unix servers
- Cheap Hosting and Identity Theft
