erlang mochiweb的测试数值

siege -q -c1000 -r100 -lsiege.log -b http://127.0.0.1:8081/hello_world[/code] 
然后mochiweb启动选项：

1使用选项：

{acceptor_pool_size, 200}


压测结果：

$siege -q -c1000 -r100 -lsiege.log -b http://127.0.0.1:8081/hello_world Transactions:                 100000 hits

2.使用选项：

{acceptor_pool_size, 20}


输出结果：

可以看到次数相同，但响应时间是20个连接池的较快，但其他数值是200个连接池的较好。显然，20 - 200间个某个特殊值可能会达到最优，因为这里面的差距没有1个数量级。
