10 GbE ports can be used with the Sun SPARC Enterprise T5120/T5220 servers by either plugging in a dual--port PCI-e Network Interface Unit (NIC) or using the on-chip dual 10GbE Network Interface Unit (NIU). There are important tuning parameters for both the NIU and PCI-e 10 GbE options.

Darryl Gove explores the question of whether there is a performance benefit proportional to the number of processors assigned work in his article "Calculating Processor Utilisation From the UltraSPARC T1 and UltraSPARC T2 Performance Counters." Gove's study involves using performance counters to estimate core load and identify potential areas for performance improvement.
