我有一台 Linux 计算机，它必须长期从多个设备（最多 30 个左右）接收流数据。
这台计算机连接到快速以太网局域网（100 Mbps），其他设备也连接到该网络，这意味着它不是专用的。
由于流数据是通过 RTP（UDP）接收的，我注意到一些数据包丢失了：可能是由于交换机/路由器，可能是由于当前的 Linux 操作系统。
在我的测试中我想优化 Linux UDP 缓冲区以管理较高的传入数据流量速率（有时可能高于 50 Mbps）。
这可能吗？在这种情况下哪个参数更关键？我在 /etc/sysctl.conf 中设置了几个参数，但它们可能是错误的……因此非常感谢任何帮助。
我附上此文件的一个示例。计算机有一个2 GB 内存卡片。
提前致谢，
