In a performance test, transactions are sent to an online transaction processing system at regular intervals. The CPU utilization of this system increases quadratically with time, while the size of the swap space and the amount of occupied disk space increases linearly with time. Complete the following:
Scalability
In a performance test, transactions are sent to an online transaction processing system at regular intervals. The CPU utilization of this system increases quadratically with time, while the size of the swap space and the amount of occupied disk space increase linearly with time. Complete the following:
1. Explain why this system has poor load scalability in its present form.
2. Identify a simple data structure and algorithm that might be in use in this application. If the development team confirms that this is indeed what is being used, explain what should be used in its place to prevent this problem.
3. Describe architectural changes that could be made to improve performance.
