WordPress Memory(RAM) Usage?

  • Hello,

    First let me start off by saying that I’m running a small control panel with Apache, Bind, PowerDNS, ProFTP, Mail shit, etc… All on a small VPS right now. The current usage(with 8 wordpress sites, that have no traffic) is around 350mb… What kind of memory usage does/will wordpress end up using? For example, I could easily put all local(small traffic) sites on a smaller server(VPS), and put larger, more demanding sites on a bigger server… I just need to know what to expect out of wordpress. And what contributes the most to the memory usage. What can I do to optimize the sites?

    Any help is appreciated..

  • Lane,

    There’s no “normal” for WordPress sites. Every site is going to vary in terms of how much memory it uses based on what you have installed into the site. E.g. if you have a shopping cart plugin installed into WordPress or have 1000’s of posts then the site is going to consume more memory than if it’s a 10 page microsite.

    If you need to control the memory use (e.g. to increase it) for some sites, you can adjust the WP_MEMORY_LIMIT settings in the wp-config.php file.

    If you’re just trying to balance the load across these sites, then you might start by installing a WordPress caching plugin like W3 Total Cache. You can use the page cache and database/object caches to reduce the load on MySQL and Apache.

    A CDN is also a good way to reduce load on the sites because it offloads the work of delivering CSS, JS, images, videos, and other static files to different servers (so that the WordPress server is only serving WordPress)
