fastupload 0.2.3 vs. common file upload 1.2.2

前天发布了fastupload 0.2.3,没想到受到了大家的关注，下载量急剧上升。首先说明一下，写fastupload纯粹是个业余爱好，拿出来几行好的代码与大家分享，后来测试了一下，确实比Apache上的common file upload要快很多。放出来两组测试数据与测试代码，限于时间与水平关系，这里不做分析与评价，只看具体数据。

测试环境还是本人的小笔记本，与第一回里测试里所用的是一模一样的，测试代码有兴趣的可以从文后的附件中下载，有兴趣的读者可以亲自测试一下。

第一组，上传三个图片，分别是348k、331k、368k，fastupload的测试结果如下
