Windows 2000 Performance Guide Help for Administrators and Application Developers By Mark Friedman, Odysseas Pentakalos The unconfirmed error reports are from readers. They have not yet been approved or disproved by the author or editor and represent solely the opinion of the reader. Here's a key to the markup: [page-number]: serious technical mistake {page-number}: minor technical mistake : important language/formatting problem (page-number): language change or minor formatting problem ?page-number?: reader question or request for clarification This page was updated September 21, 2004. UNCONFIRMED errors and comments from readers: {98} first paragraph "...it is necessary to explicitly install the Network Monitor Driver networking service to collect the Network Interface Object, for example." Since the Network Monitor Driver adds the Network Segment Object, this should be "Network Segment Object" instead of "Network Interface Object". {109} First Column (Network Interface); The calculation for % Network Utilization should be (Bytes Total/sec * 8 / Current Bandwidth) * 100. [260] 3rd paragraph; The text states "In this example the IRQs associated with the Intel 8042 10/100 Ethernet card are assigned hard processor affinity for CPU 1", referring to Figure 5- 27 on page 261. On that figure, a line corresponding to interrupt 12, controlled by the i8042prt device, is highlighted and shown with processor affinity enabled. However, this driver is the keyboard/mouse driver, not a NIC driver, so this change would not have the desired effects of setting processor affinity for the network interrupt handlers. {352} 2nd paragraph; This paragraph says that "clicking on the Maxamize Throughput for Network Applicatinos radio button sets LanmanServer Size to Large and LargeSystemCache to 1..." However, Microsoft Article 232271 says that Maxamize Throughput for Network Applications sets LargeSystemCache to 0. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache Your choices for this registry key are 0 and 1. 1 = Maximize Throughput for File Sharing 0 = Maximize Throughput for Network Applications I have verified this on a Windows NT server.
