2 Using System Monitoring Tools Before optimizing Windows Vista’s performance, monitor critical subsystems to determine how your system is currently performing.What system bottlenecks are present in your system?
3 Determining System Performance Need to do 5 things to monitor the system effectivelyCreate BaselinesIdentify System BottlenecksDetermine TrendsTest Configuration Changes and Tuning EffortsCreate Alert Thresholds
4 Creating Baselines Baseline: snapshot of current system performance Gives a point of comparison against a system that is not running optimallyCreate baselines at the following timesWhen system is first configured: no system loadRegular intervals of typical usageWhenever changes are made to the software or hardware configuration
5 Identifying System Bottlenecks Bottleneck: a system resource that is inefficient compared to the system as a wholeReliability and Performance Monitor will allow us to measure various system components in order to spot and correct bottlenecks.
6 Determining TrendsProactive Management: solve the problem before the problem happensWatch system baselines for increasing demands for RAM or Processor Time, and decreases in drive space
7 Testing Configuration Changes and Tuning Efforts When you make configuration changes or tune your computer, you should measure the effects of those changes.Follow these recommendations:Make one change at a timeRepeat monitoring with each change you makeAs you make changes, check the Event Logs.If you suspect network performance issues, compare the performance of a networked version with a local version.
8 Using Alerts for Problem Notification Reliability and Performance Monitor can alert you when certain system thresholds have been reached.Example: Alert the Administrator when disk 2 has less than 10% free space available
9 Selecting the Appropriate View Line ViewReport ViewHistogram View
13 Data Collector SetsUsed to collect data into a log so that it can be reviewed
14 Monitoring and Optimizing Memory Two areas of memory to monitor:Physical RAMPage FileImportant counters to monitor:Memory > Available MBytesMemory > Pages/SecPaging File > % UsageIf memory seems to be a bottleneck:Add RAMOptimize page file settingsRun less memory-intensive applications
15 Monitoring and Optimizing the Processor Important counters to monitor:Processor > %Processor TimeProcessor > Interrupts/SecSystem > Processor Queue LengthIf the processor seems to be a bottleneck:Run applications that are less CPU-intensiveUpgrade the CPUAdd a CPU if your computer supports multiple processors
16 Monitoring and Optimizing the Disk Subsystem Important counters to monitor:PhysicalDisk > %Disk TimeLogicalDisk > % Disk TimePhysicalDisk > Current Disk Queue LengthLogicalDisk > Current Disk Queue LengthLogicalDisk > % Free SpaceIf the disk subsystem seems to be a bottleneck:Use faster disks or hardware controllersConfirm that you are using the latest driversTake advantage of disk striping if possibleAdd another disk controller for load balancingUse Disk DefragmenterUse DFS to balance workload over a network
17 Monitoring and Optimizing the Network Subsystem Important counters to monitor:Network Interface > Bytes Total/SecTCPv4 > Segments/SecIf the network subsystem seems to be a bottleneck:Use only the network protocols you needUse network cards that use your computer’s full bus widthUse faster network cards: 100 Mbps, 1 Gbps
18 Memory Diagnostics Tool Used to test your computer’s memory
19 Problem Reports and Solutions Replaces Dr. WatsonEnables you to track system problems and check for solutions to those problems.
20 Tools to Discover System Information Task ManagerPerformance Information and Tools
30 Remote DesktopRemote Desktop is a service that allows you to remotely take control of your computer from another location. For example, you could access your work computer from home or while traveling on business.
31 Remote Assistance Used to request assistance from another user Compatible with:Windows XPWindows Server 2003Windows Vista
32 Differences between Remote Assistance and Remote Desktop Remote Desktop only allows one user to see the desktop at a time. Remote Assistance allows both local and remote users to see the desktop.Remote Desktop does not require an invitation to connect. Remote Assistance requires the remote user to invite assistance.
33 Safeguarding Your Computer and Recovering from Disaster Prepare for disaster: it’s not fun, but it’s better than being unprepared when disaster strikes.Windows Vista Recovery Techniques:Event ViewerSafe ModeLast Known Good ConfigurationStartup Repair ToolBackup and Restore CenterSystem Restore
34 Advanced Boot Options Accessed by pressing F8 at startup Options: Safe ModeSafe Mode with NetworkingSafe Mode with Command PromptEnable Boot LoggingEnable Low-Resolution Video (640x480)Last Known Good Configuration (advanced)Directory Services Restore ModeDebugging ModeDisable Automatic Restart on System FailureDisable Driver Signature EnforcementStart Windows Normally
35 Startup Repair ToolUsed to correct problems related to missing or corrupted system filesCannot repair hardware failuresCannot recover personal files that have been corrupted, damaged by viruses, or deleted
37 Backup and Restore Center Used to perform the following tasks:Back up filesRestore filesChange automatic backup settingsCreate an image of your entire computerRestore an image of your computerRestore a previous version of files on your computer using System RestoreCreate a restore point using System Protection
38 Backing Up Files with Backup and Restore Center Backup and Restore Center can back up the following:PicturesMusicVideosDocumentsTV shows recorded with Windows Media CenterCompressed files (.zip, .cab, .iso)Additional files that do not correspond to any of the other categories
39 Backup and Restore Center Limitations Backup and Restore Center will NEVER back up the following:System filesProgram filesUser Profile SettingsFiles encrypted by EFSFiles on FAT partitionsFiles in the Recycle BinTemporary FilesWeb-based
40 Creating an Image with Windows Complete PC Backup Used to create a snapshot image of your entire computer, including:ProgramsSystem SettingsFilesEverything!
41 System RestoreCreates restore points that can be used to restore system files and settings to an earlier point in timeWill not affect personal filesRestore points are created:Every dayBefore installing applications or driversBefore significant system eventsBefore restoring files with System RestoreManually upon request
