　　It's so closed to open 10 or 30 clients to do this test . And if we have more machines to run webbench , or we have a powerful server to setup trafficserver(4core CPU, 4G MEM , and so on) , I think we will have the better test result .
　　Same time & same machine , do the same test to squid3.1 & Varnish2.1.3
　　(1)Squid

　　以后在更好的硬件条件下，我会考虑更多的测试项目，将此测试重做一次，务求客观的验证不同产品之间的性能差异。初步结论：ATS相比于其他两个产品，性能更高一些。
