Operating System Notes Tuning parameters: - 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/LargeSystemCache=0, limits system cache, default 1. - Control/Session Manager/Memory Management/SystemPages=0xffffffff, sets system pages. - Tcpip/Parameters/DisableLargeSendOffload=0, enable large sends for TCP/IP. - Tcpip/Parameters/MaxFreeTWTcbs=1098000, sets maximum number of TIME_WAIT tcbs to 1,098,000. - Tcpip/Parameters/MaxHashTableSize=0x10000, sets TCB hash table size to 65,536 entries, default 512. - Tcpip/Parameters/MaxSendSegments=0x1000, max TCP segments sent consecutively to a destination, default 64. - Tcpip/Parameters/MaxUserPort=0xfffe, sets maximum open ports to 65534. - Tcpip/Parameters/NumTcbTablePartitions=32, sets number of independent TCB table segments, default 4. - Tcpip/Parameters/TcpTimedWaitDelay=60, sets TIME_WAIT parameter to 60 seconds (non-RFC 1122), default is 240. - Tcpip/Parameters/TcpWindowSize=65535, sets TCP send/receive window size, default 8192. 3 NIC IRQs bound to CPU 1,2,3; 4th NIC IRQ across CPU1,2,3 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 - SWC/Parameters/LogDrive=D, puts log file on D: drive. - SWC/Parameters/LogFileInitialSize=0xffffffff, sets initial log file size to 4 gigabytes. - SWC/Parameters/VirtualRootName=spec99, sets virtual directory name to spec99. - SWC/Parameters/VirtualRootPath=F:\wwwroot99, sets physical path where files are located. - SWC/Parameters/SmallCachingThreshold=50, max size for small files (bytes), default system-dependent. - SWC/Parameters/LargeCachingThreshold=1200000, max size for cached files (bytes), default system-dependent. - SWC/Parameters/SmallBufferSize=0x3a, memory for caching small files (MB), default system-dependent. - SWC/Parameters/LargeBufferSize=0x1b58, memory for caching large files (MB), default system-dependent. - SWC/Parameters/SwcLockedMemorySize=0x6c, size of locked memory for SWC ops (MB), default system-dependent. - TWC CAD buffers=1024, default not set. - CGI-Gateway buffers=64, default not set. Client Notes Tcpip/Parameters/MaxUserPort = 0xfffe, sets maximum open ports to 65534.
