Performance testing or load testing is a process of identifying performance issues and then solving them. It is important to conduct performance and load testing and tuning before going live, in order to eliminate the issues that can negatively impact the business. It does not matter whether you have high volumes or not; you still need performance testing. At this stage of the project, the development of custom features is complete, and functional testing is in progress. This is the time to validate the overall performance of your Finance and Operations system. The primary goal is to ensure that the solution will accept peak load without any major issues.

The key objective of this exercise is to establish a baseline for the key business scenarios, and to test and execute performance tuning and optimization to achieve the following:

• Creating a baseline of your core business scenarios.
• Simulating users and transactions in terms of concurrency and volume, and determining the load that the system can handle
• Executing performance tuning and optimization

In the end, we have to validate all the preceding considerations and ensure that the system is ready for production. It is imperative to try to accurately identify the volume of transactions, as they relate to the new system. Use the legacy system as a base starting point, and estimate the transactions in the new system by taking into consideration how transactions are generated on the new platform.
