Hey im using the latest wordpress installation and my serverload goes troug the roof when wp-cron is running, I tried to dissable it and set a manual cronjob but it's still high as hell when it's run What is the best solution to fix this ?
are you using alot of different plugins? It might help to disable each plugin, one at a time to see if that helps. Is it a multisite? IF so, disabling wp-cron is not a one step process. There is a guide on how to prevent wp-cron running automatically for multisites, here: http://www.lucasrolff.com/wordpress/why-wp-cron-sucks/ You can try reducing the intervals between running the cron job, I would not go over 10minutes, 5mins should be good enough, but what settings are you using now? There is a plugin that lets you see whats going on in the wp-cron file. Take a look here: http://wordpress.org/plugins/wp-crontrol/
