We then set the following operating system tuning parameters to reflect the WebBench recommendations in the
Microsoft Performance Tuning Guidelines for Windows Server 2003 document, available on Microsoft’s Web site.
• HKLM\System\CurrentControlSet\Services\Inetinfo\Parameters\MaxCachedFileSize to 1048576
• HKLM\System\CurrentControlSet\Services\HTTP\Parameters\UriMaxUriBytes to 1048576
• HKLM\System\CurrentControlSet\Control\FileSystem\NtfsDisableLastAccess to 1
• HKLM\System\CurrentControlSet\Services\Tcpip\Parameters\MaxHashTableSize to 65535
Network test bed configuration
To generate the WebBench workload, we used a network with 60 client PCs. Each PC contained an Intel Pentium
4 3.0 GHz with HT Technology (or faster) processor, 512 MB of system memory, a 40 GB hard drive, and a
Gigabit Ethernet network adapter. We configured each client with Windows XP Professional with Service Pack 2
and all critical updates available as of January 3, 2006.
We split the 60 clients into four segments, or subnets, of 15 clients each. We connected each segment to the
server under test via one NETGEAR GS724T Gigabit Smart Switch. To balance the load on the server and to
prevent a network throughput bottleneck, we connected each segment to a separate port of the Intel PRO/1000
PT Dual Gigabit Server adapters. Figure 6 illustrates the test bed configuration.
