Iostat & Server Performance

I'm suffering performance issues with my application, and one of my suspects is excessive IO. Here is my iostat output : Iostat & Server Performance

there are two devices has very high util´╝îand other devices doesnot have any util. Why is the problem here? Does it mean the io of the system is very excessive?

Thanks a lot
