-Remark:
-
-1. Concurrency: We only benchmark the concurrency of single process.
-1. MultipleProcess: SRS supports multiple processes by [go-oryx][oryx].
-1. HLS aonly: HLS supports audio only mode without video stream.
-1. BW check: The bandwidth check feature is used to detect the bandwidth between server and client.
-1. Security: The security includes access control, token authentication and referer check.
-1. Reload: SRS and Nginx supports reload, but nginx-rtmp doesn't.
+Comparing with other media servers, SRS is much better and stronger, for details please 
+read Product([CN][v4_CN_Compare]/[EN][v4_EN_Compare]).

-The HLS overhead is calc by: (HLS - FLV) / FLV * 100%.
-
-The overhead should be larger than this benchmark(48kbps audio is best overhead), for we fix the [#512][bug #512].

 ## Architecture
 
-SRS always use the simplest architecture to solve complex domain problems.
-
-* System arch: the system structure and arch.
-* Modularity arch: the main modularity of SRS.
-* Stream arch: the stream dispatch arch of SRS.
