<div class="section">
<p>
The latest Lucene <a href="releases.html">release</a> has the following minimum requirements:
<ul>
<li>Java 1.4.x or greater.</li>
<li>ANT 1.6.5 or greater.</li>
<li>JUnit 3.8.1 if you wish to run the unit tests.</li>
<li>CPU, Disk and Memory requirements are based on the many choices made in implementing Lucene (document size, number of documents, and number of hits retrieved to name a few.)
The <a href="benchmarks.html">benchmarks</a> page has some information related to performance on particular platforms.
Also, the <a href="http://svn.apache.org/viewvc/lucene/java/trunk/contrib/benchmark/">Contrib/benchmark</a> module has code related to benchmarking a standard set of documents.</li>
</ul>
</p>
<p>Contrib modules may have other requirements, refer to their documentation and build files for information.</p>
