What property must be increased to resolve long wait times for accessing a particular service?

To resolve long wait times for accessing a particular service, increasing the maximum number of instances per machine is essential. This property determines how many concurrent instances of a service can run on a server. When there is a high demand for a service, having more instances allows the server to handle multiple requests simultaneously, thereby reducing wait times for users.

If the number of active requests exceeds the available instances, queued requests may result in delays. By configuring a higher number of instances, you actively enhance the capacity of the server to manage more requests at once. This is crucial for services that experience peak loads or are accessed frequently by multiple users.

While network bandwidth, service timeout duration, and the number of user connections are important factors in the overall performance of services, they do not directly address the issue of handling concurrent requests as effectively as increasing the number of service instances does. Network bandwidth primarily impacts data transmission speeds, service timeout duration deals with how long a system waits before ending a request, and the number of user connections affects the total number of users that can connect at the same time but does not directly influence how many service requests the server can process concurrently.
