Adding virtual processors

Whenever you add a network VP (SOC or TLI), you also add a poll thread. Every poll thread runs in a separate VP, which can be either a CPU VP or a network VP of the appropriate network type.

Adding more VPs can increase the load on CPU resources, so if the NETTYPE value indicates that an available CPU VP can handle the poll thread, the database server assigns the poll thread to that CPU VP. If all the CPU VPs have poll threads assigned to them, the database server adds a second network VP to handle the poll thread.
