  What is it?
  -----------

  Apache JMeter is a 100% pure Java application designed to test
  and measure performance.  It may be used as a highly portable 
  server benchmark as well as multiclient load generator.
  
  Apache JMeter features include:

  Ability to load and performance test many different server/protocol types:
   o  Web - HTTP, HTTPS
   o  SOAP
   o  FTP
   o  Database via JDBC
   o  LDAP
   o  Message-oriented middleware (MOM) via JMS
   o  Mail - SMTP(S), POP3(S) and IMAP(S)
   o  MongoDB (NoSQL)
   o  Native commands or shell scripts
   o  TCP

  Full multithreading framework allows concurrent sampling by many threads
  and simultaneous sampling of different functions by separate thread groups.
  Careful GUI design allows faster Test Plan building and debugging.
  Caching and offline analysis/replaying of test results.
  Highly Extensible core:
   o  Pluggable Samplers allow unlimited testing capabilities.
   o  Several load statistics may be chosen with pluggable timers .
   o  Data analysis and visualization plugins allow great extensibility as well as personalization.
   o  Functions can be used to provide dynamic input to a test or provide data manipulation.
   o  Scriptable Samplers (BeanShell, BSF- and JSR223- compatible languages)
  

  The Latest Version
  ------------------

  Details of the latest version can be found on the Java Apache 
  Project web site (http://jmeter.apache.org/).

  Requirements
  ------------

  The following requirements exist for running Apache JMeter:

   o  Java Interpreter:

      A fully compliant Java 6 (or later) Runtime Environment is required 
      for Apache JMeter to execute.

   o  Optional jars:
   
      Some jars are not included with JMeter. 
      If required, these should be downloaded and placed in the lib directory
   
      JDBC - available from database supplier
      JMS - available from the JMS provider

   o  Java Compiler [OPTIONAL]:

      A Java compiler is not needed since the distribution includes a 
      precompiled Java binary archive. Note that a compiler is required
      if you plan to build plugins for Apache JMeter.

  Installation Instructions
  -------------------------

  Note that spaces in directory names can cause problems.

  - Release builds
  Unpack the binary archive into a suitable directory structure.
  
  - Nightly builds (Be aware that these have not been reviewed or tested)
  Unpack BOTH the _bin and _lib archives into the SAME directory structure
  
  Running JMeter
  --------------
  
  Change to the bin directory
  Run the jmeter (Un*x) or jmeter.bat (Windows) file.
  
  For Windows (2K, XP etc), there are also some other scripts.
  Drag-drop a JMX file onto one of them: 
  
  jmeter-n.cmd - runs the file as a non-GUI test
  jmeter-n-r.cmd - runs the file as a non-GUI remote (client-server) test
  jmeter-t.cmd - loads the file ready to run it as a GUI test
  
  Documentation
  -------------
  The documentation available as of the date of this release is
  also included, in HTML format, in the printable_docs/ directory,
  and it may be browsed starting from the file called index.html.

  Build instructions
  ------------------

  - Release builds
  Unpack the source archive into a suitable directory structure.
  Most of the 3rd party library files can be extracted from the binary archive
  by unpacking it into the same directory structure.
  You can also use Ant to download the required library files:
  
  ant download_jars 
  
  - Nightly builds
  Unpack the _src, _bin and _lib archives into the same directory structure.

  Please note:
  To avoid unnecessary duplication, the nightly source archives do not contain 
  the source files which are needed to run JMeter (for example properties files and scripts).

  Any optional jars (see above) should be placed in lib/opt and/or lib.
  
  Jars in lib/opt will be used for building JMeter and running the unit test,
  but won't be used at run-time.
  [This is useful for testing what happens if the optional jars are not
  downloaded by other JMeter users].

  JMeter is built using Ant.
  
  Change to the top-level directory and issue the command:
  
  ant download_jars ! only needs to be done once;
                      will download any missing 3rd party jars 

  ant

  This will compile the application and enable you to run jmeter from the bin
  directory.

  ant test [-Djava.awt.headless=true]
  
  This will compile and run the unit tests.
  The optional property definition is required if the system 
  does not have a suitable GUI display.
