### Compare
Compare SRS with other media server, more compare please read Product([CN][v1_CN_Compare]/[EN][v1_EN_Compare]).
Comparing with other media servers, SRS looks better and stronger from most points of view, please read Product([CN][v1_CN_Compare]/[EN][v1_EN_Compare]).

Remark:
1. Concurrency: The concurrency of single process.
1. MultipleProcess: SRS is single process, while [go-oryx][oryx] is a MultipleProcess SRS.
1. HLS aonly: The HLS audio only streaming delivery.
1. BW check: The bandwidth check.
1. Security: To allow or deny stream publish or play.
1. Reload: Nginx supports reload, but not nginx-rtmp.
1. Concurrency: We only benchmark the concurrency of single process.
1. MultipleProcess: SRS support multiple processes by [go-oryx][oryx].
1. HLS aonly: HLS supports delivering in audio only 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 support reload, but nginx-rtmp doesn't.
