                                Network Notes

<> Each ACEswitch 180 divided into two virtual LANs.
<> Each virtual LAN connects one card in the SUT and 3 clients.
<> MTU size = 9000 bytes.

                                 Other Notes

<> IIS settings: listen port 80, no logging, maximum performance.
<> IIS Home Directory: Access for Read and Directory Browsing Allowed

only, Application Settings permissions "none".
<> Network interrupts affinitized one NIC per CPU.
<> One disk for OS and pagefile, 4 disks OS striped for web pages, 4

disks PERC striped for logs.
<> Registry Settings:
<> - Tcpip/Parameters/MaxHashTableSize=0x10000, sets TCB hash table

size to 65,536 entries, default is 512.
<> - Tcpip/Parameters/TcpTimedWaitDelay=0x3c, sets TIME_WAIT parameter

to 60 seconds (non-RFC 1122), default is 240.
<> - Tcpip/Parameters/MaxFreeTwTcbs=1400000, sets maximum number of

TIME_WAIT tcbs to 1,400,000.
<> - Tcpip/Parameters/MaxSendSegments = 0x1000, sets maximum TCP

segments sent consecutively to a destination, default 64.
<> - Tcpip/Parameters/NumTcbTablePartitions = 32, sets number of

independent TCB table segments, default 4.
<> - NDIS/Parameters/ProcessorAffinityMask=0, forces processor that

handled interrupt to also handle that DPC, default is any processor.
<> - Inetinfo/Parameters/ObjectCacheTTL=0, sets IIS object cache

timeout to 0 seconds, default 10 minutes
<> - Inetinfo/Parameters/OpenFileInCache=0, sets number of open files

in object cache to 0
<> - Inetinfo/Parameters/MaxPoolThreads=1, sets pool threads per

processor, default is 10
<> - Inetinfo/Parameters/PoolThreadLimit=8, sets total pool threads per

system to 8
<> For each Alteon NIC:
<> - Altndis(X)/Parameters/SendCoalMax=80, sets number of send buffer

descriptors in send ring, default 333.
<> - Altndis(X)/Parameters/RecvCoalMax=20, sets number of frames

received before notifying host, default 333.
<> - Altndis(X)/Parameters/SendCoalTicks=1000, sets number of microsec.

before send buffers are returned to host, default 2.
<> - Altndis(X)/Parameters/RecvCoalTicks=1000, sets number of microsec.

before recv buffers are given to host, default 2.
<> - Altndis(X)/Parameters/JumboFrames=1, enables Jumbo Frame

support.
<> Alternate HTTP/HT.c used.  Repeated client-side calls to

gethostbyname() omitted, as approved
<>  by SPEC.  No change in measured server performance but reduction in

client load.
