Configuration

Notes

OS 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.
