Software performance tools
System performance is a function of many things, such as code, networks, hardware (client configuration, memory, CPU speed, storage capacity, etc.) and databases. It is almost impossible to predict exactly where a performance failure might occur. Software performance tools allow you to take applications to their point of failure by using virtual users. Performance testing must be precise to simulate concurrent load at exactly the same instant. With manual performance testing, human reaction times simply can't achieve and maintain the same level of concurrency as seen with automated tools.
