Question

Does Sterling make any recommendations on the number of initial threads for Integration Servers? How does this affect memory usage?

Answer

No, Sterling does not make recommendations on a setting for the number of initial threads in an Integration Server.
Sterling always recommends that customers run their servers with the minimal configurations/resources that can handle their volumes and function without any performance/functional hit (matching the customer's throughput requirement).
Setting a high number of threads/memory makes the system consume more resources, but can cause under-utilization. In addition, this may also affect the other processes through a resource crunch or a wait time for the required resource.
In general, one should give due consideration to factors such as JVM memory, database capability/throughput, nature of the Integration Server, load on the application, load on the machine, etc., before increasing the number of initial threads. Not doing so may cause situations like Integration Server slowness, entire system slowness, OOM, lock waits, deadlocks, max DB sessions reached, etc.
If the proper amount of resources is available to support the increase in number of threads, one may do so. However, Sterling does recommend that the customers do a thorough performance testing of the configuration/setting changes before rolling them onto the production system.
Customers can refer to the Performance Management Guide to know more about Sterling recommendations/suggestions in different components.
