Woocommerce maxes out CPU

Hey all,

So two days ago my site started being incredibly slow. We’re talking load times of over a minute. My hosts are A2Hosting on their Turbo package. It’s shared but when it’s normal it’s blisteringly fast. Anyways I did the plugin shuffle and found that Woocommerce itself was maxing out the CPU.

I’ve uninstalled all the other plugins, and updated WooCommerce. Updated anything else that needing updating and sure enough it still happens.

What can I do? Host is getting annoyed and limited my IOPs and number of process making things even worse. I’m going to deactivate wc and manually upload the latest files. If that doesn’t work then I dunno what to do. It’s already cost me an arm and a leg in lost sales.

Here’s the status report
