hi everyone: I do test throughput of lvs server, the mode is fullnat. Num of director is only one.The testing tool is webbentch, when throughput more than 50,000, It's not increase, I do not know what is the reason, I optimization params of kernal, include limits of open file, tcp connection. etc, thank you
