SmarteLoad enables its users to verify their systems’ ability to cope with load under any scenario. With it, they can simulate projected usage patterns and ramp load up as high as necessary, while analyzing performance bottlenecks and optimizing system performance much faster than can be done with other like tools. It’s easy to use (no scripting skills needed!), powerful, and it comes at a fraction of the price of competing products.
Webserver Stress Tool simulates large numbers of users accessing a website via HTTP/HTTPS. The software can simulate up to 10,000 users that independently click their way through a set of URLs. Simple URL patterns are supported, as well as complex URL patterns, via a Script file.
Komuso is a very simple MBean server monitoring tool. With Komuso, you can monitor any MBean server including WebLogic Server, Tomcat, JBoss, Oracle Application Server, WebSphere and just JVM locally or remotely. Komuso is unique for its simplicity. Komuso consists of only 150 lines of code.
AMD CodeAnalyst™ Performance Analyzer is a suite of powerful tools that analyze software performance on AMD microprocessors and help developers optimize application performance. It uses a profiling technique to identify performance areas and issues within the system. Using this suite of tools, developers can get visibility into overall system performance, and can navigate into different modules and functions to locate hotspots within the target application.
The RawLoadTester application is a free Open Source tool to load test websites. It does not have many features but it is useful in situations where using a more comprehensive load testing solution (e.g., Apache Flood) is not practical.
Apache JMeter is a 100% pure Java desktop application designed to load test functional behavior and measure performance. It was originally designed for testing Web Applications but has since expanded to other test functions. Apache JMeter may be used to test performance both on static and dynamic resources (files, Servlets, Perl scripts, Java Objects, Data Bases and Queries, FTP Servers and more). It can be used to simulate a heavy load on a server, network or object to test its strength or to analyze overall performance under different load types. You can use it to make a graphical analysis of performance or to test your server/script/object behavior under heavy concurrent load.
innotop is a powerful monitor for MySQL queries and status information. It is designed to monitor InnoDB transactions and internals, replication status, deadlocks, general queries and status values, and much more.
DTrace is a comprehensive dynamic tracing framework for the Solaris™ Operating Environment. DTrace provides a powerful infrastructure to permit administrators, developers, and service personnel to concisely answer arbitrary questions about the behavior of the operating system and user programs.
These tools are for use by developers so that they can create more robust applications. Especially of use to those developing multi-threaded applications in C++ with templates. Includes TCMalloc, heap-checker, heap-profiler and cpu-profiler.
