When NCA is running on a system with a lot of memory, increase this parameter to allow drivers to queue more packets of data. If a server is under heavy load, increase this parameter so modules and drivers may process more data without dropping packets or getting backlogged.
sq_max_size=0 is intended only for benchmarks or testing environments.
Solaris 8 and later releases – Do not set this parameter to 0 on production systems. If you need to change this parameter, gradually increase this value and monitor the system.
Solaris 7 and earlier releases – Do not set this parameter to 0 on production systems. If you need to change this parameter, gradually increase this value to a maximum of 100, and monitor the system.
