iperf3 Windows带宽比linux慢得多
我遇到了一个非常奇怪的问题。 我有两台服务器，一台运行redhat Linux server 7 64位，另一台运行Windows server 2012 64位。两个服务器硬件规格完全相同：iperf3 Windows带宽比linux慢得多,linux,windows,performance,bandwidth,iperf3,Linux,Windows,Performance,Bandwidth,Iperf3,我遇到了一个非常奇怪的问题。 我有两台服务器，一台运行redhat Linux server 7 64位，另一台运行Windows server 2012 64位。两个服务器硬件规格完全相同： Xeon 2.6Ghz CPU x 2, total 32 logical core 96GB ddr4 memory 1Gb dual port network card 2TB hard disk, the RAID configuration is also same. 当我在两台机器上运行ipe

如何提高Windows带宽性能 这种行为对我的项目影响极大，使用相同的套接字代码，Windows的吞吐量只有Linux的1/3
非常感谢。请尝试将TCP窗口大小8.00 KB（默认值）增加到至少64k。见下文：
希望有帮助。这与编程无关。也许你应该在超级用户社区问这个问题。你试过用Linux引导Windows机器吗？可能存在硬件差异，尽管不应该存在。Linux和Windows在每台服务器上运行，测试在本地主机上运行，Linux和Windows未连接。我正在使用TCP套接字进行IPC，我看到的是完全相同的事情，数字与您的相似。我希望社区更支持这个问题，因为它与系统架构设计有关——在Linux上运行良好的设计可能无法在Windows上运行，因为TCP带宽限制。我已经尝试在Windows注册表中增加TCP窗口大小，但重新启动后，结果仍然相同。TCP窗口大小是否会影响本地主机测试？如果它没有解决您的问题，为什么您会接受这个答案？
