bbllive

支持rtmp协议流媒体服务器,初步测试30000+,供学习用go写高并发高性能程序的同学参考
go1.6+

思想
  • 通过消息通知共享数据,锁的开销没想象的那么大
  • 对象复用,减少垃圾收集
  • 减少系统调用,通过数据包合并一次尽量发送多帧,本程序以GOP对齐后一次发送
  • 减少对象复制,本程序没有彻底实现,应该还有优化空间
还可以优化的地方
  • 读消息时一次系统调用可以读取更多消息
  • 减少数据包复制,可以通过引用计数实现
  • 可能哪里还有些内存泄漏
测试环境:
  • 2颗E5-2650 v2,64G内存,单机测试(因为没有万兆网络环境)
  • 推流工具xsplit2.7,关键帧间隔2秒,混合码流900kbps,CBR
  • 负载工具 srs-bench/sb_rtmp_load_fast
  • 每次5000并发,共跑6个sb_rtmp_load_fast进程,每进程占用100%
  • 因为是本机测试,所以软中断和负载程序占用了很大一部分CPU,所以有万兆环境+多队列万兆网卡的性能应该还可以进一步提升
  • 测试时通过vlc观看不卡,中间关闭后再开也不卡,多个vlc播放器之间延时几乎没有
30000的时候系统负载
