Operating System Notes
<> Windows 2000 available Oct-99.
Network Notes
<> Each switch connects one card in the SUT to four of the clients.
<> MTU size = 9000 bytes.
Other Notes
<> Software: Internet Information Server 5.0. Microsoft Scalable Web Cache 1.2
<> Performance boost for foreground applications---
<> Raise the priority of the foreground application, default is halfway.
<> IIS settings: listen port 81, logging disabled, expected hits fewer than 10000
<> no ISAPI filters, disable NT challenge/response.
<> IIS Home Directory: Access for Read and Directory Browsing Allowed only
<> Application Settings permissions "none".
<> Added following registry entries to Tcpip/Parameters/
<> MaxHashTableSize=0x10000---Sets TCB hash table size to 65,536 entries, default is 512.
<> MaxUserPort=0xfffe---Sets maximum user port to 65534.
<> TcpTimedWaitDelay=60---Sets TIME_WAIT parameter to 60 seconds (non-RFC 1122), default is 240.
<> MaxFreeTwTcbs=520000--Sets maximum number of TIME_WAIT TCBs to 520,000.
<> DisableTaskOffload=0--Enables checksum offloading.
<> Set registry entry NDIS/Parameters/ProcessorAffinityMask to 0---
<> Forces processor that handled interrupt to also handle that DPC, default is any processor.
<> Added following registry entries to Inetinfo/Parameters:
<> ObjectCacheTTL=0---Sets object caching time-to-live to 0 seconds.
<> OpenFileInCache=0---Sets number of active files in cache to 0.
<> MaxPoolThreads=1---Configures one thread per processor run model.
<> PoolThreadLimit=2---Allocates four thread total to handle HTTP requests.
<> For each Alteon NIC modified following driver configuration entries:
<> SendCoalMax=80--Sets number of send buffer descriptors in send ring.
<> RecvCoalMax=20--Sets number of frames received before notifying host.
<> PCIReadMax=256--Sets maximum number of bytes per PCI read burst.
<> SendCoalTicks=1000--Sets number of microsec. before send buffers are returned to host.
<> RecvCoalTicks=1000--Sets number of microsec. before recv. buffers are given to host.
<> JumboFrames=1--Enables Jumbo Frame support.
<> SWC configured with 1 thread per NIC affinitized to same CPU as NIC.
<> One 9GB 10KRPM disk for OS, 4 9GB 10KRPM disk for web pages, logs and pagefile.
<> Alternate HTTP/HT.c used. Repeated client-side calls gethostbyname() ommitted
<> as approved by SPEC.
<> No change in measured server performance but reduction in client load.
