This is a good book that covers the topics well. Much of the information on counters and their impact actually comes from the Help Index, without additional comments or added value. Too bad, because the synergy and impact of multiple counters on performance is one area that really could use more thorough coverage.
The added value that an outstanding performance tuning guide would provide is missing from most of the Windows 2000 performance tuning guides that have been published. The best current resources at this point continue to be experience and digging through the Microsoft Technet whitepapers.
If you need a handy shelf reference, this one's as good as the other ones out there, though I believe the Microsoft Windows 2000 Performance Tuning and Technical Reference is slightly better for both begining and experienced performance tuners.
