To address High Other Time in your Appian instance, what step is recommended?

When dealing with High Other Time in an Appian instance, adding additional Engine Replicas is the recommended approach. The "Other Time" metric generally refers to time spent in various overhead tasks that aren't directly attributed to CPU utilization or I/O operations. This can be associated with processing requests and managing resources efficiently.

Adding Engine Replicas allows for better distribution of user requests across multiple processing engines, which can help reduce the load on individual engines. By doing this, you can enhance the overall throughput and responsiveness of the application. This scaling approach helps to manage workloads effectively, especially during peak usage times, thereby reducing the time spent in "Other Time" as requests are handled more quickly and evenly across the replicas.

Other options, such as adding more application servers, adjusting memory settings, or increasing CPU cores, can also improve performance but might not specifically address the inefficiencies in processing loads that are leading to high Other Time. Therefore, while they can contribute to overall system performance, they may not directly target the issue as effectively as increasing Engine Replicas does.
