SAP Memory Analyzer

Home Page

Categories: Profiling - Debugging

Author: SAP

Latest version: 1.1.1
Added 2007-11-24

Heap analyzer that helps you find big chunks of memory and identify who is keeping these objects alive.

SAP Memory Analyzer was developed to analyze productive heap dumps with hundreds of millions of objects. Once the heap dump is parsed, you can re-open it instantly, get the retained size of single objects and approximate the retained size of a set of objects. The Analyzer is (relatively) low on resource consumption, so you can analyze multi-GB heap dumps on 32 bit boxes.
SAP Memory Analyzer supports HPROF binary heap dumps, a de-facto standard of Sun supported also by other vendors: Sun, SAP and HP JDK/JVM from version 1.4.2_12 and 5.0_7 and 6.0 upwards. IBM doesn't support HPROF binary heap dumps.
SAP Memory Analyzer is based on Eclipse 3.3 and needs a 1.5 JDK.

Profiler4j

Home Page

Categories: Profiling - Debugging

Latest version: 1.0 Beta 2
Added 2006-07-04

Open-source CPU profiler for Java that supports remote profiling and on-the-fly configuration.
Profiler4j has two main parts:
- a profiling agent that runs in the same JVM as your application
- a remote console that connects to the remote agent and allows the user to view the profiling data and change settings

Features include:
- Based on bytecode instrumentation.
- You can define rules to select which packages, classes, and methods must be profiled. Even more, you can change these rules without restarting your application. Only profiled methods are instrumented. The remaining code runs at 100% of the original speed. Thanks to JVMTI (introduced in J2SE1.5), Profiler4j can redefine classes as many times as needed while the JVM is running.
- Add a JVM parameter to your application and you're ready to go.
- 100% Java. No native library or executable is required.
- UI includes: call graph view that shows the "hot path"; call tree view; memory monitor; thread status monitor; list of loaded classes that can be profiled and their current instrumentation status; load/save settings

Java profiler providing diagnostics on memory usage, performance and test coverage.

JProbe Suite includes:
- JProbe Memory: for proactively discovering, diagnosing and resolving memory allocation issues such as memory leaks (loitering objects) and excessive garbage collection activity (object cycling) that can lead to out-of-memory system crashes and slower overall system performance.
- JProbe Performance: for proactively discovering, diagnosing and resolving code bottlenecks such as expensive methods, deadlocks and stalled threads that can lead to slow application performance and limit scalability.
- JProbe Coverage: for proactively assessing the completeness and accuracy of test runs in development and QA – enhances development and QA collaboration in creating more complete test suites.

JProbe also offers an Eclipse plug-in that provides code performance analysis and problem resolution directly within the Eclipse Java IDE.

Latest version: 1.0
Added 2007-09-17

JFC/Swing benchmark suite.
JFCMark is a benchmark suite created to measure performance of JFC/Swing and related APIs.
All tests report performance measured in units specific to their particular scenarios (e.g. repaints/sec) so that the results could be used for comparative performance evaluation of different client-side Java VMs available for the system under test. You may also use JFCMark to compare hardware, operating systems and video drivers with respect to Java UI performance.

JFCMark is designed to execute on J2SE environments versions 1.3 and 1.4.

Categories: Profiling - Debugging

Author: Neotys

Latest version: 1.0
Added 2005-03-23

Load testing tool for web applications (J2EE, ...).
By simulating a large number of users accessing your application, NeoLoad tests the robustness and the performance of the server under different loads. A test report pinpoints errors and bottlenecks, so you can focus on your slow JSP pages and code, or server configuration issues.

Through the test, NeoLoad answers these questions: How many users does my site handle? Will my site crash under load? What are the response times?

Key features:
- GUI for designing your tests (no scripting, wizards).
- Can dynamically extract links and data while the test is running to inject them in the scenario.
- Browser-based recorder: browse your application to record your scenario.
- System monitoring: get statistics from your servers (CPU, Memory, …).
- Data replacement: log in the virtual users with different accounts, submit forms changing the values.
- Data extraction: extract generated links and forms.
- Content validation: check page content under load.
- Reporting: generate a test report (HTML/PDF/XML).
- SSL: record and replay secured pages.
- IP spoofing: mandatory to test IP based load balancers.
- Written in Java and multi-platform (Windows, Linux, Solaris).
- Can generate a large amount of traffic by using additional load generators.
