The Industry Leader Among Profiling Tools

CPU and memory profiling has never been easier, and smarter at the same time. YourKit has developed a revolutionary approach to profiling applications at both development and production stages, bringing unparalleled benefits to professional Java developers on all platforms, including Windows, Linux, Solaris SPARC/Intel, and Mac OS X.

• Powerful analysis capabilities: CPU and memory hot spots with devoted views; unique snapshot comparison; memory leak detection; memory distribution reports; measuring of shallow and retained sizes of objects; reporting utility.
• On-demand profiling: With this cutting-edge feature, you can enable profiling only when you need it, with the application running at its full speed for the rest of the time. For example, you can analyze the current heap state at any moment during application runtime by capturing a memory snapshot. This feature is extremely useful for profiling huge applications - with zero overhead.
• Free embedding into production: You are eligible to distribute a profiling DLL with your real-world commercial applications free of charge. This helps you ease your product maintenance and improve your customer support.
• J2EE support: Non-intrusive profiling of high-scale production applications; easy integration with application servers; innovative automatic deobfuscator.
• Java 5/6 support: YourKit utilizes all of the advanced Java 5/6 features, including unique support for JVMTI.
• Quick and easy installation: Straight-forward installation process, with the most reasonable defaults; seamless integration with popular IDEs and application servers; minimum extra configuration.
• J2ME support: First in the market memory profiling of mobile applications.
• User-friendliness and usability: Light-weight and intuitive scenario-based user interface; keyboard support; report filtering for quick and deep analysis; profiling natively incorporated into supported IDEs to be available from the most obvious and reasonable places.
• Flexible licensing policy: Multi-platform and multi-processor licensing: commercial, floating, educational, and open source licenses available .

1.parasoft Jtest同样不错。
Jtest的静态代码分析能自动检测代码是否符合超过800条的程序编码规范和任意数量的用户定制的编码规则，帮助开发者避免出现这些隐蔽且难以修复的编码错误。
在测试运行时定位内存泄漏
捕捉配置代码运行的真实行为以生成Junit测试用例
可完整集成于Eclipse, RAD, JBuilder

Jtest详细介绍，可参考：

2.还有一个Jennifer是web应用服务器应用性能管理解决方案。
Jennifer详细参考：http://www.innovatedigital.com/JENNIFER.shtml
JENNIFER不仅能够监视CPU、内存使用量等系统资源的使用状况，还可以监视在应用后台程序中所发生的服务Transaction。以往的系统管理解决方案只能监视CPU、内存、磁盘使用量,当应用后台程序中发生了性能瓶颈问题时，很难确认问题的根本原因。而JENNIFER可以提供直观高效的视觉化性能监控界面，不仅实际操作者、就连项目管理者以及高层经营者都能简便地有效地使用它。

动态分析java类，java方法

对于已执行的所有SQL响应时间与SQL运行所使用的BIND变量，在不造成性能低下的情况下进行追踪。可依据SQL响应时间及被调用的应用程序等关联性，对问题进行深度分析。
