Network Notes

Each ACEswitch 180 connects one card in the SUT and three clients.
MTU size = 9000 bytes.

Other Notes

IIS settings: listen port 81, no logging, expected hits fewer than 10000, no ISAPI filters, NT challenge/response disabled.
IIS Home Directory: Access for Read and Directory Browsing Allowed only, Application Settings permissions "none".
Network interrupts affinitized one NIC per CPU.
SWC configured with 1 thread per NIC affinitized to same CPU as NIC.
One 9GB 10KRPM disk for OS and pagefile, 2 9GB 10KRPM disks striped for web pages and logs.
Registry Settings:
- 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=580000, sets maximum number of TIME_WAIT tcbs to 580,000.
- NDIS/Parameters/ProcessorAffinityMask=0, forces processor that handled interrupt to also handle that DPC, default is any processor.
- Inetinfo/Parameters/ObjectCacheTTL=0, sets IIS object cache timeout to 0 seconds, default 10 minutes
- Inetinfo/Parameters/OpenFileInCache=0, sets number of open files in object cache to 0
- Inetinfo/Parameters/MaxPoolThreads=1, sets pool threads per processor, default is 10
- Inetinfo/Parameters/PoolThreadLimit=4, sets total pool threads per system to 4
For each Alteon NIC:
- Altndis(X)/Parameters/SendCoalMax=100, sets number of send buffer descriptors in send ring.
- Altndis(X)/Parameters/RecvCoalMax=20, sets number of frames received before notifying host.
- Altndis(X)/Parameters/SendCoalTicks=1000, sets number of microsec. before send buffers are returned to host.
- Altndis(X)/Parameters/RecvCoalTicks=1000, sets number of microsec. before recv buffers are given to host.
- Altndis(X)/Parameters/JumboFrames=1,enables Jumbo Frame support.
Alternate HTTP/HT.c used. Repeated client-side calls to gethostbyname() omitted, as approved
by SPEC. No change in measured server performance but reduction in client load.
