Continuing WP 3.5 functions causing high CPU

Since updating to WP 3.5 in Dec. I have noticed that my CPU% on my cpanel has increased drastically to the point I am eliminating a lot of plugins and the like to keep my host happy. I am on a shared server and they don’t want me to exceed 10%CPU.

Something as simple as editing a post and hitting the update button will cause the CPU to jump to 50%. I am using WP Super Cache and it doesn’t seem to make a difference.

I never had this problem with WP 3.42. I am hoping someone will have some ideas as to what is going on before I manually download to WP 3.4.2.

Thank you for reading this and any help or answers you can provide.
