										<content:encoded><![CDATA[<p>早些时候就在google到Whoosh和xapian的性能对比文章，只是由于文章被墙，今天才翻墙看到。<br />
文章是xapian作者写的。就文章里的对比结果来看，whoosh和xapian的性能差距还是比较明显。索引和搜索的速度有近4倍的差距，在full cache情况下的性能差距更是达到了60倍。<br />
除算法原因外，whoosh的纯python定位也决定了whoosh很难达到其他c/java的搜索引擎库的速度。<br />
当然，whoosh的优势是易用性，在考虑性能的情况下whoosh不是首先。<br />
