Server-Class Machine Optimizations Server Systems Overview Before reviewing this information, ensure you are familiar with the “Server-Class Machine Requirements” on page 2. This document includes a list of TT products that require server-class machines. Note: Most recommendations and optimizations in this document will be across all server-class machines; however, exceptions will be noted for specific products.
Hardware and Operating System — Windows Server 2003 (32-bit) Service Pack and Registry TT supports Windows Server 2003 for all server-class machines. TT no longer supports Windows 2000 Servers. Note: Two additional hot fixes should be installed on server-class machines: • Hotfix 917114: Will resolve the issue when a server experiences “An operation on a socket cannot be performed because the system lacks sufficient buffer space or because a queue is full.” • Hotfix 931311: The heavy use of Winsock programs may exhaust the "non-paged pool memory" of a Microsoft Windows Server 2003-based computer. This behavior is likely to occur if the Winsock program is dealing with both "Out-of-Band (MSG_OOB) traffic" and "standard TCP traffic." In this situation, you may receive various error messages. Also, you may experience poor performance. Additionally, the system may stop responding (hang). ** Hotfix 917114 is included with SP2, but if a client is running SP1, it would need to be installed separately. Hotfix 931311 is not included with SP2 and should be installed separately as well. In addition, the following configuration changes must be made to the registry on each. (These changes are made in conjunction with the NIC configuration changes in the next section.) 1. Add the following DWORDS (and values) to… HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\ Parameters. • ArpCacheLife = ffffffff • ArpCacheMinReferencedLife = ffffffff • Tcp1323Opts = 00000001 • EnableTCPA = 00000000 • EnableRSS = 00000000 • EnableTCPChimney = 0000000 • DisableTaskOffload = 00000001 2. Add IgnorePushBitOnReceives = 00000001 as a new DWORD (and value) to… HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AFD\ Parameters. 3. Add TcpAckFrequency = 00000001 as a new DWORD (and value) to…HKEY_LO- CAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\ Parameters\Interfaces\. Note: See Appendix B for explanations about these Registry settings.
