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

以後在更好的硬件條件下，我會考慮更多的測試項目，將此測試重做一次，務求客觀的驗證不同產品之間的性能差異。初步結論：ATS相比於其他兩個產品，性能更高一些。
