* This option specifies whether to optimize the network driver for a normal
environment, a minimized CPU utilization environment, or a maximized network
performance environment. You may choose to use a larger percentage of CPU
resources under DOS in order to improve network throughput. In multitasking
environments, choose the Minimize CPU Utilization option to save the resources of
the CPU for other tasks. If no other applications are making major demands on CPU
resources, you can choose the Maximize Network Performance option.
