Examples

For example, if the adapter is represented by "Local Area Connection 6" and "Local Area Con-

nection 7"

-st Single stream traffic scenario.

This option must be followed by one or two connection names for an Ethernet adapter.

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

For single port stream tuning type:

perf_tuning.exe -s -c1 "Local Area Connection 6" -c2 "Local Area Connection 7"

or to set one adapter only:

perf_tuning.exe -s -c1 "Local Area Connection 6"

For single stream tuning type:

perf_tuning.exe -st -c1 "Local Area Connection 6" -c2 "Local Area Connection 7"

or to set one adapter only:

perf_tuning.exe -st -c1 "Local Area Connection 6"

For dual port streams tuning type:

perf_tuning.exe -d -c1 "Local Area Connection 6" -c2 "Local Area Connection 7"

For forwarding streams tuning type:

perf_tuning.exe -f -c1 "Local Area Connection 6" -c2 "Local Area Connection 7"

For manual tuning of the first adapter to use RSS on CPUs 0-3:

perf_tuning.exe -m -c1 "Local Area Connection 6" -b 0 -n 4

In order to restore defaults type:

perf_tuning.exe -r -c1 "Local Area Connection 6" -c2 "Local Area Connection 7"
