Process isolation is another optimization technique that controls the number of GIS-service instances in a process. You can either perform high or low process isolation and each has its merits. By having more instances in a single process, you are performing a low-isolation technique. By lowering the number of instances, you are spreading your instances into multiple processes, thus performing a higher isolation. In Server, having a single instance in a process is referred to as high isolation.
By isolating each instance in a single process the instance will have its own dedicated area in the memory heap. This means a service with high isolation is less likely to experience downtime and failure. Even if a process is terminated or a memory leakage happened in one of the processes, only one instance will be recycled while the rest of the instances will remain available. Since each instance requires a dedicated process in this approach, this will...
