Our blog is lightning fast thanks to WP-Super Cache, but we're having hiccups, and now we're noticing this Cron issue..
Our blog is doing this Cron thing right before it goes offline for about 30 seconds. It's always when we are accessing the dashboard, saving a post, or publishing a post, or clicking on a link in the dashboard.
And we installed WP-Super Cache in like January, so I'm not convinced that this problem was totally fixed.
I believe that these are related to other issues that we've had with WP-Super Cache causing "high load" as you call it- so much that is makes http://edreach.us unreachable for about 30secs to 1 minute.
Is there a setting I should change in the backend that would help with this?
