如何对Web表单文件上传进行压力测试？

Question

我需要测试一个上传文件的Web表单.每次上传的文件大小约为10 MB.我想测试服务器是否可以处理超过100个同时上传,并且仍然对网站的其余部分保持响应.

我们办公室提交的重复表格将受到我们当地DSL线路的限制.服务器位于异地,带宽较高.

基于经验的答案会很棒,但欢迎任何建议.

使用与Apache捆绑的ab(ApacheBench)命令行工具(我刚刚发现了这个很棒的小工具).与cURL或wget不同,ApacheBench设计用于在Web服务器(任何类型的Web服务器!)上执行压力测试.它也会产生大量的统计数据 下面的命令将发送HTTP POST请求包括文件test.jpg到http://localhost/ 100倍,最多4名并行的请求.

ab -n 100 -c 4 -p test.jpg http://localhost/

它产生如下输出:
