压测的时候，如果在应用包里加入runtime包，会对压测产生非常严重的干扰。

测试1：开启runtime包

[luwenwei@test-weishi01v ~]$ siege -c  --time=15s -q -f /tmp/SafeBizEngine.siege.

Lifting the server siege...      done.

测试2：把runtime包注释掉

[luwenwei@test-weishi01v ~]$ siege -c  --time=15s -q -f /tmp/SafeBizEngine.siege.

Lifting the server siege...      done.

Transactions:                 hits

实验1,2对比发现：引入runtime包后的错误率很高，从而影响压测的关键数据QPS。
