                           Notes/Tuning information

SUT Notes
    IIS settings: maximum performance.
    IIS Home Directory: Access for Read & Write, Scripts & Executables.
    IIS Virtual Directory spec99 points back to web server root, low application protection.

Operating System Notes
    IntFilter tool used to bind NIC IRQ to first CPU.
    Tuning parameters:
    - AFD/Parameters/TransmitWorker = 32, adjusts system default thread, default 16.
    - Control/FileSystem/NtfsDisableLastAccessUpdate = 1, prevents updating LastAccess time stamp on NTFS directories, default 0.
    - Inetinfo/Parameters/ObjectCacheTTL=0xffffff, sets IIS object cache timeout, default 10 minutes
    - Inetinfo/Parameters/ListenBackLog = 1000, default 25.
    - Inetinfo/Parameters/AcceptExTimeout = 1, sets time for accept ex socket to wait for receive, default 120.
    - Inetinfo/Parameters/MaxPoolThreads = 20, maximum network request threads per processor, default 10.
    - NDIS/Parameters/ProcessorAffinityMask = 0, forces processor that handled interrupt to also handle that DPC, default any processor.
    - Tcpip/Parameters/MaxHashTableSize=0x10000, sets TCB hash table size to 65,536 entries, default is 512.
    - Tcpip/Parameters/MaxFreeTwTcbs=400000, sets maximum number of TIME_WAIT tcbs to 400,000.
    - Tcpip/Parameters/MaxUserPort = 0xfffe, sets maximum open ports to 65534.
    - Tcpip/Parameters/NumTcbTablePartitions = 16, sets number of independent TCB table segments, default 4.
    - Tcpip/Parameters/TcpTimedWaitDelay = 0x3c, sets TIME_WAIT parameter to 60 seconds (non-RFC 1122), default is 240.
    - Tcpip/Parameters/TcpWindowSize = 17520, sets TCP send/receive window size, default 8192.
    Intel NIC registry settings:
    - NumTxDescriptors = 768, Number of buffers available for transmit acceleration, default 256.
    - ChecksumRxTcp = 1, offloads RX checksums to NIC, default 0.

HTTP API Notes
    Microsoft ISAPI for IIS 5.0 compiled with VC++ 6.0.

Hardware Notes
    One 9GB disk for OS and logs, 4 18GB disks striped for web pages
