. For example, the UI Tier can be dozens of servers, hundreds of servers, or even thousands of servers. The number of servers required for each Tier is configured based on actual needs. The actual requirement is to check the hardware resource utilization of this Tier server. For example, CPU, memory, disk read/write, and so on. If it is very high, you must add a new server to deploy the same application of this Tier to the new server. So that new serv
【Abstract] A large and medium-sized library information system involves many technologies and solutions. This article focuses on some content related to Web server performance. I have the honor to be one of the project owners to participate in the design of a digital information system in a large library and the development of Web application software.

The key is that if you don't take the time to learn these tools, the tools that should help you will hurt you. 2, excessive or unnecessary log Logging is a powerful weapon in the Debug ToolPak that can help you identify the exceptions that may occur during a specific period of time during application execu
How the Java GC works, how to optimize GC performance, and how to interact effectively with the GCA goodJavaProgrammers must understandGC, how to optimize GC performance, how to interact effectively with GC, because some applications have higher performance requirements, such as embedded systems, real-time systems, etc
. The actual requirement is to check the hardware resource utilization of this tier server. For example, CPU, memory, disk read/write, and so on. If it is very high, you must add a new server to deploy the same application of this tier to the new server. So that new servers can share some pressure. In fact, this is to enable applications to support high scalability. There is a hardware load balancing between each tier, and then it is the service inter

. second, the management page The auction site contains a management report that takes a few seconds for the database server to create such a report. Long report generation This is important because we may have multiple administrators monitor the system's performance while trying to avoid rebuilding the report every time the administrator accesses it. To do this, we will encapsulate the entire page within an appli
Most Active Server Pages (ASP) applications use string concatenation to create data that is rendered to the user in HTML format. This article compares several methods for creating this HTML data stream, and in certain cases some methods are superior to other methods in performance. This article assumes that you already have some knowledge of ASP and visual Basic programming. Directory Brief introduction ASP Design string concatenati
the State management of long-time data (such as cursors. You cannot tolerate lag or pause when an operation is being processed by your application. If an operation is time-consuming and resource-consuming, You need to detach the operation and perform asynchronous processing on it, so that your application remains responsive and users can process their transactions. This principle applies to disk read/write

As any mobile platform continues to develop and its applications are constantly improved, quality becomes crucial if development is successful. Today, users require that they decide to install Android applications on their own devices to respond quickly and with reasonable performance. If those applications fail to provide exciting features and stable user experience, they will soon be uninstalled. This article describes the top 10 key points for Andr
Many programmers spend a lot of time tuning application-level performance bottlenecks as they address JVM performance issues, and when you finish reading this series you will find that I might look at this kind of problem more systematically. I've said that the JVM's own technology limits the scalability of Java enterp

Although Android smartphones and tablets are faster than a day, developers must remember that their applications are still running in a resource-intensive environment, this environment relies primarily on batteries and processors that are unmatched by the latest desktop or laptop.
