 In the picture `cppnet_1` used `REUSE_PORT`，`cppnet_2` used `EPOLLEXCLUSIVE`.    
-When use `REUSE_PORT`, the overall efficiency is basically the same as that of `muduo`. When the concurrency is less than 1000, `cppnet` performs better, When more than 1000, `muduo` performed better.   
+When use `REUSE_PORT`, efficiency is slightly better than `muduo`.      
 When use `EPOLLEXCLUSIVE`, the overall performance is better than `muduo`(muduo does not support the `EPOLLEXCLUSIVE` setting).

 图中`cppnet_1`为使用`REUSE_PORT`，`cppnet_2`为使用`EPOLLEXCLUSIVE`。    
-使用`REUSE_PORT`时，整体效率上与`muduo`基本持平，在1000并发以下时，`cppnet`表现更优，1000发以上时，`muduo`表现更优。    
+使用`REUSE_PORT`时，整体效率稍稍优于`muduo`。    
 在使用`EPOLLEXCLUSIVE`时，性能整体都优于`muduo`(muduo尚未支持`EPOLLEXCLUSIVE`设置)。
