During application maintenance for the customer, I noticed some performance problems under high load conditions. Theoretically, increasing the load on the application will reduce the performance, but I think the performance drop rate is much higher than the load increase. At the same time, I also found that, performance can be improved by changing the logic of the application. To learn more about this, we need to perform some performance analysis. At this time, we naturally need to use some perf

monitoring interface. After the installation is complete and set up as the developer version of TC Server, then deploy the application on the TC server. I look at the Insight interface, which is a good way to monitor classes and methods, and see how much time is spent to complete this method. I can also see the input parameter values, as well as the return values. Since my application is spring-based, spring insight can provide very useful data. The TC server plug-in configuration is similar to

In the development process of Java program, it is unavoidable to encounter memory usage, performance bottleneck and so on. javaprofiler Tools Help developers locate these issues quickly and effectively, making them an important tool in the Java development process. At present, there are many kinds of JavaProfiler tools on the market, this article will briefly introduce several common tools, and compare them

cron. Its basic function is to continuously establish and test software projects, so that developers can easily integrate changes into projects, making it easier for users to obtain new builds. Jenkins can also monitor the execution of external running tasks, such as cron jobs, even Tasks running on a remote computer.Apache Continuum is an enterprise-level continuous Integration Server.
