SAP ASE spawns separate threads to perform network polling.
However, separate threads may not show significant performance gains when running with a low engine configuration. SAP ASE 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 inline to avoid this contention. When you set network polling mode to inline, one engine performs polling, eliminating the need for a separate thread. On the Linux platform, setting the network polling mode to inline reduces CPU usage by using high-resolution sleep APIs.
