Dell : PowerEdge 8450/700 || NC SPECweb99
Microsoft : IIS 5.0 and SWC 3.0 ||
||
===============================================================================
SPEC has determined that this result was not in compliance with the
SPECweb99 run and reporting rules. Specifically, the result did not meet
the 3 month availability requirement in the SPECweb99 run rules due to a
change in availability of Microsoft SWC 3.0.

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=64, 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.
Alteon NIC settings in registry:
- PciReadMax=128, sets maximum number of bytes per PCI read burst, default 0xffffffff.
- LargeSend=1, enables large sends.
- HybridLen=54, threshold in bytes that the driver decides to DMA versus copy, default 128.
- HostTracing=0 (off), disables NIC driver logging events, default 1 (on).
Client Notes
Tcpip/Parameters/MaxUserPort = 0xfffe, sets maximum open ports to 65534.
Other Notes
SWC 3.0 Configuration:

SWC/Parameters/LogDrive=G, puts log file on G: 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=500, max size for small files (bytes), default system-dependent.
