SPECweb99 Result =============================================================================== || 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. =============================================================================== PERFORMANCE | Conforming Simultaneous Iteration | Connections ---------------+---------------------------- 1 | NC 2 | NC 3 | NC ---------------+---------------------------- Median | NC =============================================================================== Availability Dates All Hardware Jun-2000 HTTP Software Mar-2001 Operating System Mar-2001 Supplemental System Mar-2001 Hardware Vendor Dell Model PowerEdge 8450/700 Processor 700MHz Pentium III Xeon # Processors 8 cores, 8 chips, 1 core/chip Primary Cache 16KBI+16KBD on chip Secondary Cache 2MB(I+D) Other Cache None Memory 32 GB Disk Subsystem 1 9GB 10KRPM drive, 8 16GB 15K RPM drives Disk Controllers Onboard Symbios SCSI Other Hardware 7 Alteon ACEswitch 180 Software Operating System Windows 2000 Datacenter Server File System NTFS Other Software New TCP/IP & Alteon driver hotfixes HTTP Software Vendor Microsoft HTTP Software IIS 5.0 and SWC 3.0 API TWC 3.0 Server Cache None Log Mode Binary CLF Test Sponsor Test Date Dec-2000 Tested By Dell SPEC License 55 Network # of Controllers 7 Network Controllers Alteon AceNIC 1000SX # of Nets 7 Type of Nets Gigabit Ethernet Network Speed 1Gb/s MSL (sec) 30 (Non RFC1122) Time-Wait (sec) 60 (Non RFC1122) MTU 1500 Clients # of Clients 35 Model Dell Precision 410 Processor 450MHz Pentium II # of Processors 2 Memory 128MB Network Controller Alteon AceNIC 1000SX Operating System Windows 2000 Professional Compiler Microsoft Visual C++ 6.0 Benchmark Configuration Requested Connections 7300 Fileset Size (MB) 23477.68 =============================================================================== Notes/Tuning information SUT Notes 1 disk for OS 6 disk software RAID0 stripe for fileset, 2 disk software RAID0 stripe for logs. 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: Each NIC IRQ bound to a different CPU. 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. SWC/Parameters/LargeCachingThreshold=1200000, max size for cached files (bytes), default system-dependent. SWC/Parameters/SmallBufferSize=0x40, memory for caching small files (MB), default system-dependent. SWC/Parameters/LargeBufferSize=0x6590, memory for caching large files (MB), default system-dependent. SWC/Parameters/SwcLockedMemorySize=0x80, size of locked memory for SWC ops (MB), default system-dependent. =============================================================================== Test Run Details Run Conforming Percent | Throughput Response ops/sec/ Kbits/ Num Connections Conform | ops/sec msec loadgen sec => 1 NC NC | NC NC NC NC 2 NC NC | NC NC NC NC 3 NC NC | NC NC NC NC
