How to monitor and improve the performance of IIS 5.0

Today I'm going to show you how to monitor and improve the performance of IIS 5.0 servers, and that's just something I've summed up from some information and practice, and come out and talk about it, J.
We will discuss the following aspects:
1, Memory (memory), memory performance directly affect the performance of other components, I think more than CPU and hard disk performance is more important, in IIS5.0 we should note that sufficient memory resources to our web server to bring higher performance. About specific to such as: IIS Object Cache, and so on due to the time of the reasons I will be introduced later.
2, to solve the bottleneck of the processor, we try to use tools to test the single CPU and multiple CPUs under the operation of IIS, and to avoid the processor as a bottleneck affecting the performance of the server, the performance of the processor directly affects the Web customer response time.
3, the network I/O, to take into account our network in a certain period of the largest data transfer, what settings can play the maximum performance of the service. Specific will be in the future, but often to see AH.
4, Web applications, try to monitor the operation of IIS with applications that have little impact on server performance.
5, monitor the load that the security mechanism brings, to be able to know how the security mechanism such as windoows authentication and SSL brings to the system load.
These are my views on how to improve the performance of IIS, I hope you can have some benefits, I will write something for you to discuss every day. No, there are questions you can write to me or put forward in the forum.
