What is the first step in finding the performance bottle necks? How do you find them?

Performance bottlenecks can be found by using monitors in the controller. By seeing the metrics of the monitors we can find out if there are any performance issues. Normally by seeing the transaction response time, throughput, no of hits per sec etc... We can find out if any performance bottleneck issues. Normally these monitors might include webserver monitors, application server monitors, database server monitors or network monitors.
