Three common Java application performance challenges

Java is a great language. It manages memory and teaches Object-Oriented Programming (IDEAS) so that we can better use it for coding. In addition, it is indeed a language for "writing once and running everywhere. However, Java applications may encounter some common performance challenges that developers and applications are familiar. Memory leakage One of the biggest advantages of Java is its ability to manage memory models. Java cleans up objects

Architecture of large-scale asp.net application systems-how to achieve high performance and high scalability

. 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

Five techniques for improving Node.js application performance
