	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 对MooseFS有了一定的了解，现在可以压压它的性能了，使用的是iozone IO测试工具。测试命令为：<br/>./iozone -a -n 512m -g 4g -i 0 -i 1 -f /mnt/mfs/logs/test.tar.gz -Rb ./iozone.xls -C<br/><strong>测试说明</strong><br/>1、/mnt/mfs/logs/test.tar.gz大小为9.2G，大于服务器物理内存(8G)。<br/>2、获取挂载的分区的write、re-write、read、re-read数据。<br/><br/><strong>测试数据</strong><br/>一、reader report<br/><a href="https://blog.liuts.com/attachment.php?fid=121" target="_blank"><img src="https://blog.liuts.com/attachment.php?fid=121" class="insertimage" alt="点击在新窗口中浏览此图片" title="点击在新窗口中浏览此图片" border="0"/></a><br/><a href="https://blog.liuts.com/attachment.php?fid=122" target="_blank"><img src="https://blog.liuts.com/attachment.php?fid=122" class="insertimage" alt="点击在新窗口中浏览此图片" title="点击在新窗口中浏览此图片" border="0" width="710"/></a><br/><br/>二、re-reader report<br/><a href="https://blog.liuts.com/attachment.php?fid=123" target="_blank"><img src="https://blog.liuts.com/attachment.php?fid=123" class="insertimage" alt="点击在新窗口中浏览此图片" title="点击在新窗口中浏览此图片" border="0"/></a><br/><a href="https://blog.liuts.com/attachment.php?fid=124" target="_blank"><img src="https://blog.liuts.com/attachment.php?fid=124" class="insertimage" alt="点击在新窗口中浏览此图片" title="点击在新窗口中浏览此图片" border="0" width="710"/></a><br/><br/>三、write report<br/><a href="https://blog.liuts.com/attachment.php?fid=127" target="_blank"><img src="https://blog.liuts.com/attachment.php?fid=127" class="insertimage" alt="点击在新窗口中浏览此图片" title="点击在新窗口中浏览此图片" border="0"/></a><br/><a href="https://blog.liuts.com/attachment.php?fid=128" target="_blank"><img src="https://blog.liuts.com/attachment.php?fid=128" class="insertimage" alt="点击在新窗口中浏览此图片" title="点击在新窗口中浏览此图片" border="0" width="710"/></a><br/><br/>四、re-write report<br/><a href="https://blog.liuts.com/attachment.php?fid=125" target="_blank"><img src="https://blog.liuts.com/attachment.php?fid=125" class="insertimage" alt="点击在新窗口中浏览此图片" title="点击在新窗口中浏览此图片" border="0"/></a><br/><a href="https://blog.liuts.com/attachment.php?fid=126" target="_blank"><img src="https://blog.liuts.com/attachment.php?fid=126" class="insertimage" alt="点击在新窗口中浏览此图片" title="点击在新窗口中浏览此图片" border="0" width="710"/></a><br/><br/><strong>结果分析</strong><br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 从图表中可以看出，写IO可达到将近10MB/s，很接近单块磁盘的IO性能，因测试chunkserver只有两台，在多台时该值会有所偏低，与chunkserver服务器数成反比，此时读IO会成正比。<br/><br/>如大家有什么疑问或感兴趣的话题可以通过weibo与我交流：<a href="http://t.qq.com/yorkoliu" target="_blank">http://t.qq.com/yorkoliu</a><br/>Tags - <a href="https://blog.liuts.com/tags/moosefs/" rel="tag">moosefs</a> , <a href="https://blog.liuts.com/tags/%25E6%2580%25A7%25E8%2583%25BD/" rel="tag">性能</a>
