Flag Description
-s Single port traffic scenario.
This option can be followed by one or two connection names. The tuning will restore the
default settings on the second connection and performed on the first connection.
This option automatically sets:
• SendCompletionMethod = 0
• RecvCompletionMethod = 2
• *ReceiveBuffers = 1024
• In Operating Systems support NDIS6.3:
RssProfile = 4
Additionally, this option chooses the best processors to assign to:
• DefaultRecvRingProcessor
• TxInterruptProcessor
• TxForwardingProcessor
• In Operating Systems support NDIS6.2:
RssBaseProcNumber
MaxRssProcessors
• In Operating Systems support NDIS6.3:
NumRSSQueues
RssMaxProcNumber
-d Dual port traffic scenario.
This option must be followed by two connection names. The tuning in this case is code-
pendent.
This option automatically sets:
• SendCompletionMethod = 0
• RecvCompletionMethod = 2
• *ReceiveBuffers = 1024
• In Operating Systems support NDIS6.3:
RssProfile = 4
