What is CPU related Bottle necks? And how to fix them?

As many of us think, CPU bottle neck is the simplest among all to find out and of course to solve. In UNIX environment VMSTAT, IOSTAT will give the CPU resources and by analyzing you can confirm if there is a CPU problem. Normally if system resources are 90% or more then you can confirm that it’s a CPU bottleneck. In windows environment ‘Perfmon’ will give the CPU resources utilization. Simply got to command prompt and type ‘perfmon’, press enter.
Once you are decided that there is an issue, and then there are two ways to solve. The simplest way is to increase the CPU capacity either by buying additional memory or by buying physical hard disk. And the other alternative is to tune the application so as to utilize min CPU resources.
