                                Network Notes

<> All of the 4 networks were configured as 1000Mbit/sec with 9K frame

size.
<> The 4 networks were isolated by configuring the network switch to

host 4 virtual LANs.
<> Each of the four networks included one card in the server under test

and four clients.

                                 Other Notes

<> Performance Boost for Foreground Application=NONE --Do not raise the

priority of the foreground application, default is halfway.
<> Disable IIS Windows NT Challenge/Response --Disables IIS user

information encryption, default is enabled.
<> Added Registry Entry InetInfo/Parameters/ObjectCacheTTL=0x0

--Disables caching of IIS open descriptor, default is caching enabled for 10

minutes.
<> Added Registry Entry InetInfo/Parameters/OpenFileInCache=0x0

--Number of open file handles in cache.
<> Added Registry Entry InetInfo/Parameters/MaxPoolThreads=1

--Specifies maximum network request threads per processor, default is 4.
<> Added Registry Entry InetInfo/Parameters/PoolThreadLimit=4

--Specifies maximum pool threads in system, default is 2 * #MB.
<> Added Registry Entry Tcpip/Parameters/MaxFreeTwTcbs=510000

--Increases the TCB timewait table to 510000 entries.
<> Added Registry Entry Tcpip/Parameters/MaxHashTableSize=0x10000

--Sets TCB hash table size to 65,536 entries, default is 512.
<> Added Registry Entry Tcpip/Parameters/TcpTimedWaitDelay=0x3c --Sets

TIME_WAIT parameter to 60 seconds (non-RFC 1122), default is 30.
<> Added Registry Entry Tcpip/Parameters/MaxUserPort=0xfffe --Sets the

number of the TCP user ports to 65,536
<> Set NDIS/Parameters/ProcessorAffinityMask to 0 --Forces processor

that handled interrupt to also handle that DPC, default is any processor.
<> One 4GB 7200K RPM SCSI disk for OS, 1 10K RPM disk for page file, 4

4GB 7200K RPM disks for web pages, 6 9GB 10K RPM disks for logs.
<> SWC configured with one thread per NIC affinitized to same CPU as

NIC.
<> For each Alteon NIC:
<> Altndis(X)/Parameters/SendCoalMax=0x14 (Max buffer descriptors sent

before updating send producer index, default: 333)
<> Altndis(X)/Parameters/RecvCoalMax=0x28 (Max buffer descriptors

received before updating receive producer index, default: 333)
<> Altndis(X)/Parameters/SendCoalTicks=0x3e8 (Max clock ticks (in usec)

the NIC waits before updating send producer index, default: 2)
<> Altndis(X)/Parameters/RecvCoalTicks=0x3e8 (Max clock ticks (in usec)

the NIC waits before updating receive producer index, default: 2)
