The ability to maintain the performance of the system when both workload and resources increase proportionally.

Step 1: Understand the question The question is asking for an explanation of the concept of maintaining system performance when both workload and resources increase proportionally.

Step 2: Define the concept System performance refers to the ability of a system to efficiently and effectively carry out its tasks or functions. Workload refers to the amount of work or tasks that need to be processed by the system. Resources, in this context, refer to the available hardware, software, and other components that the system relies on to perform its tasks.

Step 3: Explain the concept When both workload and resources increase proportionally, it means that the system is experiencing an increase in the number or complexity of tasks that need to be processed, while also having an increase in the available resources to handle those tasks.

Maintaining system performance in this scenario means ensuring that the system can handle the increased workload without a significant decrease in its efficiency or effectiveness. This requires the system to effectively utilize the additional resources to process the increased workload.

Step 4: Provide an example For example, let's consider a web server that experiences a sudden increase in the number of users accessing its website. This increase in workload can put a strain on the server's resources, such as CPU, memory, and network bandwidth. To maintain system performance, the server needs to efficiently distribute the incoming requests among its available resources, ensuring that each request is processed in a timely manner. This may involve load balancing techniques, such as distributing the workload across multiple servers or optimizing the server's resource allocation.

Step 5: Summarize the concept In summary, the ability to maintain system performance when both workload and resources increase proportionally involves effectively utilizing the available resources to handle the increased workload without a significant decrease in efficiency or effectiveness. This can be achieved through techniques such as load balancing and resource optimization.
