压力测试 (stress testing) 工具：SLAMD (Distributed Load Generation Engine)

公司同事介绍了一个做压力测试的工具软件：SLAMD (http://slamd.com)

根据这个网站自己的介绍，它可以做“LDAP, HTTP, SMTP, IMAP, and POP, or any database that can be accessed via JDBC”－－也就是所有能够用JDBC的地方。

网上没有更多的资料，这个工具现在是开源软件，但是好像已经两年没有什么更新了。不知道应用是否广泛。看来需要花点时间读读它的源程序了。

它的官方网站介绍如下：

SLAMD Distributed Load Generation Engine The SLAMD Distributed Load Generation Engine (SLAMD) is a Java-based application designed for stress testing and performance analysis of network-based applications. It was originally developed bySun Microsystems, Inc., but it has been released as an open source application under theSun Public License, which is anOSI-approved open source license. The main site for obtaining information about SLAMD ishttp://www.slamd.com/, but it is also available as ajava.net project. SLAMD was originally developed for the purpose of benchmarking and analyzing the performance of LDAP directory servers, and it is the most powerful and flexible tool available for this task. However, it is also well-suited for testing other kinds of network applications and has been used for things like Web servers and Web-based applications, relational databases, and mail servers. It can also be used for non-network based applications (and in fact, it is used for comparing things like CPU power and memory latency across a number of different kinds of systems), although its distributed nature makes it ideal for systems that can be accessed remotely. SLAMD provides a Java-based API to make it possible to quickly develop custom workloads, and it also contains an embedded scrīpting engine that can make it easy to stress applications using protocols like LDAP, HTTP, SMTP, IMAP, and POP, or any database that can be accessed via JDBC. It also includes tools for recording and playing back TCP traffic, and a utility for intercepting LDAP communication and writing it as a scrīpt that may be executed in the SLAMD scrīpting engine.
