循环次数： 100000

结果：

代码

------ Test started: Assembly: Pixysoft.Framework.Reflection.dll ------

reflection
    Time Elapsed:        514ms
    CPU time:        500,000,000ns
    Gen 0:             0
    Gen 1:             0
    Gen 2:             0

dynamic
    Time Elapsed:        366ms
    CPU time:        234,375,000ns
    Gen 0:             132
    Gen 1:             1
    Gen 2:             0

1 passed, 0 failed, 0 skipped, took 1.11 seconds (Ad hoc).

结论：性能比较接近，证明反射的性能不是非常差。

2. AOP 使用IMessageSink的attribute模式 VS RealProxy VS DynamicProxy

循环： 10000

结果：

代码

------ Test started: Assembly: Pixysoft.Framework.Reflection.dll ------

aop
    Time Elapsed:        961ms
    CPU time:        953,125,000ns
    Gen 0:             71
    Gen 1:             0
    Gen 2:             0

real
    Time Elapsed:        72ms
    CPU time:        78,125,000ns
    Gen 0:             8
    Gen 1:             0
    Gen 2:             0

dynamic
    Time Elapsed:        59ms
    CPU time:        62,500,000ns
    Gen 0:             8
    Gen 1:             0
    Gen 2:             0

1 passed, 0 failed, 0 skipped, took 1.20 seconds (Ad hoc).

比微软的RealProxy性能好一点点。

3. 反射获取设置值 VS 动态编译获取设置值 VS BeanMap获取设置值

循环 100000

结果：

代码

------ Test started: Assembly: Pixysoft.Framework.Reflection.dll ------

reflect
    Time Elapsed:        2,703ms
    CPU time:        2,671,875,000ns
    Gen 0:             39
    Gen 1:             0
    Gen 2:             0

dynamic
    Time Elapsed:        834ms
    CPU time:        843,750,000ns
    Gen 0:             457
    Gen 1:             0
    Gen 2:             0

beanmap
    Time Elapsed:        861ms
    CPU time:        828,125,000ns
    Gen 0:             205
    Gen 1:             0
    Gen 2:             0

1 passed, 0 failed, 0 skipped, took 4.52 seconds (Ad hoc).

性能上beanmap和dynamictype接近，但是处理方便。

4. 反射获取Type信息 VS 动态编译获取Type信息

循环 100000

结果：

代码

------ Test started: Assembly: Pixysoft.Framework.Reflection.dll ------

reflection
    Time Elapsed:        268ms
    CPU time:        250,000,000ns
    Gen 0:             72
    Gen 1:             0
    Gen 2:             0

emit with handler cache
    Time Elapsed:        229ms
    CPU time:        218,750,000ns
    Gen 0:             19
    Gen 1:             0
    Gen 2:             0

1 passed, 0 failed, 0 skipped, took 0.59 seconds (Ad hoc).

再次说明了，反射的性能实际上不差。

5. RealProxy实现POJO VS 动态编译实现POJO VS 直接创建POJO

循环 100000

结果：

代码

------ Test started: Assembly: Pixysoft.Framework.Reflection.dll ------

proxy
    Time Elapsed:        3,090ms
    CPU time:        2,843,750,000ns
    Gen 0:             498
    Gen 1:             0
    Gen 2:             0

dproxy dynamic constructor
    Time Elapsed:        122ms
    CPU time:        125,000,000ns
    Gen 0:             47
    Gen 1:             1
    Gen 2:             0

direct
    Time Elapsed:        4ms
    CPU time:        0ns
    Gen 0:             2
    Gen 1:             0
    Gen 2:             0

1 passed, 0 failed, 0 skipped, took 3.41 seconds (Ad hoc).

可见动态编译的得到的对象再进行操作，性能是非常高的！
