Notes

Operating System Notes

NIC bound to first CPU via IntFiltr
App response optimized for applications, default background services
Registry tunes:
- Control/FileSystem/NtfsDisableLastAccessUpdate=1, prevents updating LastAccess time stamp on NTFS directories
- Tcpip/Parameters/NumTcbTablePartitions=32, sets number of independent TCB table segments, default 4
- Tcpip/Parameters/MaxHashTableSize=0x10000, sets TCB hash table size to 65,536 entries, default 512
- Tcpip/Parameters/TcpTimedWaitDelay=0x3c, sets TIME_WAIT parameter to 60 seconds (non-RFC 1122), default 240
- 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/TcpWindowSize=17520, sets TCP send/receive window size, default 8192
- NDIS/Parameters/ProcessorAffinityMask=0, forces processor that handled interrupt to also handle that DPC, default any processor
Intel NIC:
- NumTxDescriptors=4096, number of descriptors to send packets, default 256
- TcpSegmentation=1, enables TCP segmentation offload, default 0
- FlowControl=0, disables flow control, default 1
- ChecksumRxTcp=1, offloads RX checksums to NIC, default 0

HTTP Software 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
- 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=4, maximum network request threads per processor, default 10
- Inetinfo/Parameters/PoolThreadLimit=8, sets total pool threads per system, default 2*MB RAM

Client Notes

NIC settings:
- Flow Control=Auto, default None
- RxCoalescingTicks=0, interrupt when RxMaxCoalescedFrames reached, default 360
- RxMaxCoalescedFrames=40, received frames before interrupt generated, default 15
- RxStdDescCnt=400, receive descriptors, default 200
