100% cpu usage just by browsing through wp-admin

  • Any ideas what can cause such a thing? It’s a pretty large site with over 10,000 posts and 15,000 tags. Worked well until recently.

  • Does this occur with default unedited theme and no plugins activated?

    Any site updates/modifications ‘recently’?

    Thank your for your reply and sorry for the poor details.
    I have deactivated the plugins and tested it using the Twenty Twelve theme but nothing changed. It looks to me like a database issue, it’s a bit weird that the CPU goes to 100% just by listing posts in wp-admin (assuming that I have blocked all other access to the server).

    I’ve cleaned up wp_options as much as I could, deleted post revisions and some junk from wp_postmeta too.. but can these cause such a huge resource usage? Any ideas how to debug this on a shared hosting?

    Who is the host? Some are better than others. With 10K posts and 15K tags, you’re pushing the limits of a cheap, shared host. Probably time for a VPS.
