Notes on IIS Optimization

Let's learn how to optimize IIS today. Here, we will explain the considerations for optimizing IIS. To avoid future headaches, you should pay attention to optimizing IIS when installing IIS. We know there are two reasons for poor IIS server service performance. One is artificial, that is, the Administrator has not optimized or configured the IIS server during installation or configuration.

The other is objective. As the service type and number of visitors increase, the original hardware configuration of the server cannot meet the requirements. Therefore, the hardware configuration needs to be improved. For example:

1. To improve performance and save resources, only the required protocols should be run. Many administrators did not pay attention to this. I have seen NetBEUI, TCP/IP, and IPX protocols installed on a Web Service-only machine. Obviously this is unreasonable.

2. the IIS server should be optimized and set to an independent server. Do not let the server handle the extra load required by the domain controller. Imagine: Can the server provide the IIS service while responding to user logon?

3. You can distribute the Page Swap files of the NT Server to multiple physical disks. Note that multiple "physical disks" are not valid when distributed across multiple partitions. In addition, do not place the Page Swap file in the same partition as the WIndows NT boot area.

4. Optimizing IIS's use of Disk Images or disk Zone sets can improve disk read performance.

5. log records should adopt file records instead of logging to ODBC data sources. In addition, you can increase the memory buffer capacity used to record logs during the recording period to reduce disk activity. The default size of the buffer is 64 KB.

6. When optimizing IIS, it is best to store all the data in a separate partition. Then, run the disk fragment program regularly to ensure that no fragments exist in the partition where the Web server data is stored. Using NTFS helps reduce fragments. I recommend using Norton's Speeddisk to quickly sort out NTFS partitions.

7. Although SSL can provide quite reliable encrypted transmission. However, the additional overhead will cause the IIS server to speed down, especially when processing large files. Therefore, you should only perform SSL encryption on directories that do need to be protected.

Here we will explain how to optimize IIS.
