Operating System Notes

Registry tunes:
- AFD/Parameters/TransmitWorker=32, adjusts system default thread, default 16.
- Control/FileSystem/NtfsDisableLastAccessUpdate=1, prevents updating LastAccess time stamp on NTFS directories.
- Control/Session Manager/Memory Management/IoPageLockLimit=65536, increases I/O pages limit to 64MB, default 512KB.
- Tcpip/Parameters/NumTcbTablePartitions=16, sets number of independent TCB table segments, default 4.
- 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=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 is any processor.
Intel NIC settings:
- NumTxDescriptors=4096, number of descriptors to send packets, default 256.
- TcpSegmentation=1, enables TCP segmentation offload, default 0.
- NumCoalesceBuffers=768, number of coalesce buffers for transmit acceleration, default 128.
- 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=20, maximum network request threads per processor, default 10.

Hardware Notes

One disk OS and logs, 2 disk SW RAID-0 stripe for file set and logs.
