Dịch vụ chỉ mục Windows là một dịch vụ được thiết kế để chỉ mục tất cả các tập tin trên máy tính của bạn vào một cơ sở dữ liệu. Máy tính của bạn sau đó có thể tìm kiếm thông qua tất cả các tập tin của bạn nhanh hơn. Ý tưởng đằng sau dịch vụ là rất tốt, nó sẽ cắt giảm mạnh số lượng thời gian cần thiết để tìm kiếm ổ cứng của bạn. | 244 Part II Increasing Your System s Performance Disable Indexing Service The Windows Indexing Service is a service that is designed to index all of the files on your computer into a database. Your computer can then search through all of your files faster. The idea behind the service is great it will drastically cut down on the amount of time that is needed to search your hard drive. Although this is a great benefit you have to consider the downside of this feature. In order to create a database of files the service has to continuously monitor the files on your computer and import basic file details into its database when new files are found. The monitoring is not always done in real time but at times you will notice it running. The most common symptom of this service working is when you are reading something on your computer and all of a sudden your hard drive starts making a lot of noise as if it is working really hard. That is because it is working hard to update the Indexing Service s database. Just like any other service that starts up when the system does the Indexing Service takes up memory quite a bit of memory compared to other services. In fact the service takes up exactly 4364KB of memory when the service first starts up on your computer. Eventually about 30 seconds after the service has started the amount of memory used decreases to 306KB. This Figure 10-8 Indexing Service Properties.

Also it is running at the lowest CPU priority so you can be sure that it won t interfere with other applications very much at all. Personally I rarely use the Search feature of Windows XP and would much rather disable the Indexing Service and take the performance hit the one time every few
