NeoLoad

Home Page

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.

Author: Excelsior

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: IBM

BIPTK (Bytecode Instrumentation Profiling Toolkit for Java) is an Eclipse-based toolkit that helps developers and performance specialists exploit bytecode instrumentation for the purpose of profiling Java applications.
BIPTK includes a library for generating profiling traces, an Eclipse plug-in GUI for visualizing the traces, and some working examples of instrumenting code with Eclipse TPTP Probekit.
The Bytecode Instrumentation Engine captures timing events from the Java application, and the library makes the correlations and saves traces in XML format.
The Eclipse plug-in is an editor for profiling traces, helping in the analysis, and visualizing for each method and every child call; it also enables navigation of the whole call tree in order to identify the major causes of performance degradation.

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.

Categories: JSF - JSP - Tag libraries - AJAX, Profiling - Debugging

Author: Desiderata Software

Latest version: 1.0
Added 2007-02-07

Tool for debugging JSP (Java Server Pages) scripts.
Given a JSP, JspDebug will generate a Java file that's close to the JSP, and can be debugged using any IDE that has a debugger. The structure of this Java file is specially designed for ease of debugging. Once the bug has been found, the fix can be put into the original JSP. Before adding the fix to the original JSP, the Java file generated by JspDebug can also be modified to see if a particular fix will solve the problem.

Features include:
- During debugging, a String variable named _content is available. It can be examined or watched in the debugging IDE, and it will contain the JSP output until the current statement.
- Supports Servlet 2.3 and JSP 1.2
