You can’t tell anything from that image, apart from there was some high usage. To know what it’s from you’d need a lot more detail.
Unless you can find more details about what processes and files are using the CPU resources the only thing you can do is try to disable plugins and themes until you find a change in the CPU usage.

Slowness/high CPU usage could be due to (but not limited to):
– A poor or memory intensive theme. Switch to the WordPress default theme and test loading time and see if you see a difference. If you do, may be your theme can be re-written to be more efficient.
– Poor or memory intensive plugins. One by one disable plugins and test loading time and see if you see a difference. If you do, may be that plugin can be re-written to be more efficient.- your server is slow (e.g., “process hang”, overload, you get a lot of visitors, other problems, etc.); generally, every inexpensive host out there is slow.
– I don’t know if you use CloudFlare or not but if you do I would suggest deactivating it and seeing if it helps. Also sometimes a good purge of the cache on CloudFlare can help.
– Lots of images can cause slowness. Also images loaded without compression.
– Lots of external content (facebook/ gravatar/ google adds, etc.) and redirects in general tends to slow sites down.

Oh, thanks for the great list! I didn’t know about Pingdom and GMetrix. Will try
Can I contact you on email or skype regarding this? 🙁
