There are a few proven methods you can use to improve the performance of your code before you get into the specifics. Here’s what you can do as you’re coding to keep errors to a minimum and improve that performance. Perform profiling and load testing: Performing regular tests will quick...
JProfiler或者perf的剖析(Profiling)数据是非常有用的参考,任何不基于实际运行数据的猜测往往会让我们误入歧途,接下来我们需要做的大多数时候都是“找热点 -> 优化” ,然后“找热点 -> 优化”,然后一直循环。找热点不是那么难,难在准确的分析代码的逻辑然后判断到底它应该消耗多少资源(通常都是CPU),然后制定优化...

By profiling your Java application, you can discover the methods that execute in your application and for how long. Using these metrics, you can determine ways to improve the performance of your system. In this blog post, I’ll walk you through the support that IntelliJ IDEA has for profilin...
With a programming language/environment such asJavathe performance of our Java code may be a concern. I often use an old-fashioned "quick-and-dirty" way to measure the performance of Java code, and I'll share that method in this brief article. ...
When profiling, it is usually worthwhile to have separate measurements available for the communication subsystems. Wrapping the JDBC classes provides an effective technique for measuring database calls. [Article discusses how to create JDBC wrapers to measure the performance of database calls]. If mo...
XRebel does things traditional profiling tools can’t. It allows developers to trace the impact of their code from beginning to end -- even in distributed applications. This, combined with real-time Java performance metrics, makes XRebel a must-have tool for any Java developer. With XRebel,...
Android Studio provides a robust static analysis framework and includes over 365 different lint checks across the entirety of your app. Additionally, it provides several quick fixes that help you address issues in various categories, such as performance, security, and correctness, with a single click...
Java SE プラットフォーム・ファミリには、Java SE Runtime Environment (JRE)とJava Development Kit (JDK)の 2 つの主要製品があります。 Java Runtime Environment (JRE) Java Runtime Environment (JRE) は、Java プログラミング言語で記述されたアプレットやアプリケーションを実行するための...
Memory profiling is an essential aspect of performance optimization for any Java application. It involves monitoring and analyzing the runtime behavior of your application in terms of memory usage, object creation, and garbage collection. Goals of memory profiling ...
