When should mass operations be carried out to minimize system performance impact?

Carrying out mass operations during night or off-peak times is strategically beneficial for minimizing system performance impact. This timing allows for the execution of resource-intensive tasks when user activity is at its lowest, thereby reducing competition for system resources such as CPU, memory, and bandwidth. When users are not actively utilizing the system, it ensures that these operations can complete more quickly and without causing delays or slowdowns for the end-users.

Scheduling mass operations during periods of high user activity—such as peak hours—can lead to performance bottlenecks, where the operations interfere with regular business processes and impact user experience. Performing these tasks at any time without consideration for user load can similarly compromise system performance. While executing operations solely on weekends might seem appealing, it may not always align with business hours or other operational considerations, making night or off-peak hours a more flexible and practical choice for such activities.
