“Avg Net I/Os per Check” reports the average number of network I/Os (sends and receives) per check for all Adaptive Server engine checks that took place during the sample interval.
The sp_configure parameter i/o polling process count specifies the maximum number of processes that Adaptive Server runs before the scheduler checks for disk and network I/O completions. Tuning i/o polling process count affects both the response time and throughput of Adaptive Server.
For more information about configuration parameters, see Chapter 5, “Setting Configuration Parameters,” in the System Administration Guide, Volume 1.
If Adaptive Server engines check frequently, but retrieve network I/O infrequently, you can try reducing the frequency for network I/O checking.
