Notes

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

Tuning parameters:
- Tcpip/Parameters/TcpTimedWaitDelay=0x3c, sets TIME_WAIT parameter to 60 seconds (non-RFC 1122), default is 240
- Tcpip/Parameters/MaxFreeTwTcbs=400000, sets maximum number of TIME_WAIT tcbs to 400000
- Tcpip/Parameters/MaxUserPort=0xfffe, sets maximum open ports to 65534
- Tcpip/Parameters/TcpWindowSize=17520, sets TCP send/receive window size, default 8192
- NDIS/Parameters/ProcessorAffinityMask=0, The initiating processor services DPC events, default 0xffffffff
- Inetinfo/Parameters/ListenBacklog=1000, default 10
- Inetinfo/Parameters/ObjectCacheTTL=0xffff, sets IIS object cache timeout, default 10 minutes
- Inetinfo/Parameters/AcceptExTimeout=0x1, sets time for accept ex socket to wait for receive, default 120
Alteon NIC settings in the registry:
- StatTicks=0, Number of ticks between stat updates, default 100000
- SendCoalTicks=10000, sets number of microsec before send buffers are returned to host, default 1000
- RecvCoalTicks=10000, sets number of microsec before recv buffers are given to host, default 1000
- SendCoalMax=10, sets number of frames sent before notifying host, default 20
- RecvCoalMax=80, sets number of frames received before notifying host, default 20
- RxFlowControl=0(off), receive flow control, default 1 (on)
- IntCount=10000, default 1000. It is the total number of "loops" DPC would process for events like receives and transmits before yielding to the OS.

HTTP API Notes

ISAPI for IIS5.0 compiled with VC++ 6.0

Hardware Notes
