[resolved] WP-Cron - heavy CPU consumption? (5 posts)

    I switched from WP Super Cache to W3 Total Cache, and I'm very happy with the switch. The only issue I noticed is that WP-Cron consume significantly more CPU, and is dropping scheduled tasks (e.g. Backwpup, scheduled posts, etc.).

    As example, the daily wp-cron consumption was 9.54% 1.0785 GPU a month ago, while it's 24.41% 21.9978 GPU after the upgrade to W3TC

    Since then, cron jobs didn't start reliable anymore.

    I've seen many posts about this, without a specific answer. Is there any hot patch, or will there be an update that addresses it?

    Worked around it by:

    - Replacing BackWPUp (consumed up to a second page load time, measured by P3)
    - Turning off WP-Cron during each load, and scheduled a call to it hourly via a "true" cron job.

    Works great now, load is minimal.

    Sorry to necro a resolved issue, but I've been noticing that wp_cron is really hogging things on my server and I feel like it's probably a related issue. I don't use BackWPUp, pretty sure the only thing that I have Cron'ed is Google Sitemap.

    Not really certain how best to proceed, but this seemed like the most relevant thread.
