17. System Log Events • System log • Primary log file for most system services, drivers, and processes • Events • Error • Information • Warning Guide to MCDST 70-271

18. Application Log Events • Contains event messages that • Can be generated by Windows XP Professional native applications or services • Events • Error • Information • Warning Guide to MCDST 70-271

19. Security Log Events • Place where all event details generated by auditing are recorded • Events • Success Audit • Failure Audit Guide to MCDST 70-271

20. Performance Options • Used to adjust system performance based on applications and virtual memory • Paging file • Portion of disk space where the operating system stores memory pages not in active use Guide to MCDST 70-271

21. Performance Options (continued) Guide to MCDST 70-271

22. Setting Application Priority • Priority levels • 0–15: User-accessible process priorities • 16–31: System-accessible process priorities • 0–6: Low user range • 4: Low value • 5: BelowNormal value (as set in Task Manager) • 7: Normal (default setting for user processes) • 8–15: High user range Guide to MCDST 70-271

23. Setting Application Priority (continued) • Priority levels (continued) • 10: AboveNormal value • 13: High value • 16–24: Realtime values accessible to Administrator-level accounts • 24: Realtime value • 25–31: Realtime values accessible to operating system only Guide to MCDST 70-271

24. Recognizing and Troubleshooting Bottlenecks • Bottlenecks • Occur when a limitation in a single component slows down an entire system • Always exist in any computer • No single monitor that can easily identify all possible problems Guide to MCDST 70-271

25. Common System Bottlenecks • Disk bottlenecks • Most likely problem when disk-related counters increase more dramatically than others • Memory bottlenecks • System bottleneck caused by a lack of available physical or virtual memory • Processor bottlenecks • Occur when demands for CPU cycles from active processes and operating system cannot be met Guide to MCDST 70-271

26. Common Network Bottlenecks • Network bottlenecks • Caused by excessive traffic on the network medium to which computer is attached • Not typical on most Windows XP Professional machines Guide to MCDST 70-271

27. Eight ways to Boost Windows XP Professional Performance • Buy a faster machine • Upgrade an existing machine • Install a faster CPU • Add more L2 cache Guide to MCDST 70-271

28. Eight ways to Boost Windows XP Professional Performance (continued) • Add more RAM • Replace the disk subsystem • Increase paging file size • Increase application priority Guide to MCDST 70-271

29. Optimizing Performance for Mobile Windows XP Users • Make sure • Network interface appears higher in the binding order • File synchronization settings for folder redirection and Offline Files do not require machines to synchronize when running on battery • Mobile users understand how to use hibernate and standby modes on their battery-powered machines • Offline Files are copied to user machines before they leave the network environment Guide to MCDST 70-271

30. Optimizing Performance for Mobile Windows XP Users (continued) • Refresh rates should be extended to avoid unnecessary network access • Configure group policy’s Configure Slow link speed control to define threshold at which a link is considered slow as opposed to fast Guide to MCDST 70-271
