                            Operating System Notes

<> OS version used: Microsoft Windows 2000 Advanced Server Release Candidate 2

                                Network Notes

<> Each ACEswitch 180 connect one card in the SUT to 4 or 5 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 9GB 10KRPM disk for OS and pagefile, 4 9GB 10KRPM disks striped

for web pages and 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=1700000, sets maximum number of

TIME_WAIT tcbs to 1,700,000.
<> - 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.
<> - Tcpip/Parameters/TcpWindowSize = 65535, sets TCP send/receive

window size, default 8192.
<> - 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
<> - Session Manager/Memory Management/SystemPages=0xffffffff,

increases default system page table entries, default set based on physical

memory size.
<> - SWC/Parameters/LogDrive=G, sets drive letter for log file
<> - SWC/Parameters/LogFileInitialSize=0xffffffff, sets initial log

file size
<> For each Alteon NIC:
<> - SendCoalMax=80, sets number of send buffer descriptors in send

ring, default 20.
<> - 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.
