High Resource Usage Tip?

[vekou]

Hi, I was just suspended for High Resource Usage. I only have Wordpress installed and no cron job is running in the background. I just need a tip on what plugin might have caused it. My currently installed plugins are:

• AddThis Social Bookmarking Widget
• Advertising Manager
• Akismet
• All in One SEO Pack
• Free CDN
• Google XML Sitemaps
• Simple Twitter Connect
• WordPress Importer
• WordPress Mobile Pack
• WP-Memory-Usage
• Wp-Thumbie

My guess is that it's either Google XML Sitemaps or the Wp-Thumbie. But based on what I know the sitemap plugin can only use a lot of memory when building the sitemap, but I wasn't building a sitemap nor triggered an event to build a sitemap. The Wp-Thumbie plugin uses Tim-thumb to generate a thumbnail on the fly, so it might also be a candidate in causing high resource usage.
I can simply disable those two, but I need to make sure of the real cause to prevent a loss of functionality on my website.

Thanks.

Hello,

The only way to do this would be to disable all of the plugins, and start enabling them one by one. There is no easy way to tell which is causing the high resource usage.

Thank you, I have been doing it since I unsuspended myself, but I'm still not sure what it is, since I don't know when I would get a high CPU usage, on what could trigger it. Is there a list of notable wordpress plugins that are notorious in terms of CPU usage? I've been searching the forums, but so far only caching plugins are known, but I already disabled a cache plugin around a month ago.
Thanks.
