Adaptive Server 15.7 spawns separate threads to perform network polling. However, separate threads may not show significant performance gains when running with a low engine configuration. Adaptive Server may suffer from contention between engines and the network threads when it runs with a low engine configuration on machines with a lower number of CPUs.
Set the network polling mode configuration parameter to avoid this contention. When you set network polling mode to inline, one engine performs polling requiring a separate thread. On the Linux platform, setting the network polling mode reduces CPU usage by using high-resolution sleep API.
