I can say it's all wrong and I can say that this is how it is supposed to be. Without detailed info I don't think anyone can help you.
But here are some pointers:
-What thread or http request is causing the hight load, are there more then one.
Find the top 10 of most CPU consuming threads and analyse them. Every microsecond you can shave off, is 1...
- Get a MYSQL tuning script and see if there is room for improvement in your my.cnf
- Log all slow queries and analyse them, index whereever needed, otherwise try to rewrite queries to be faster.
But the main thing is: log and analyse. It might take a week to just get one part a microsecond faster but tuning and retuning is a must.
