问题描述

如何在MAC OS X中获得最大的TCP接收/发送窗口?

How to get maximum TCP Receive/Send window in MAC OS X?

Linux中有两个ctl. /proc/sys/net/core/rmem_max-最大TCP接收窗口(NET_CORE_RMEM_MAX) /proc/sys/net/core/wmem_max-最大TCP发送窗口(NET_CORE_WMEM_MAX)

There are two ctl in Linux. /proc/sys/net/core/rmem_max - Maximum TCP Receive Window (NET_CORE_RMEM_MAX) /proc/sys/net/core/wmem_max - Maximum TCP Send Window (NET_CORE_WMEM_MAX)

但是我找不到如何在Mac OS中获取这些参数.

but i couldn't find how to get these parameters in mac os.

有人知道吗?

我在MAC OS X中找到了以下ctls: net.inet.tcp.recvspace，net.inet.tcp.sendspace，kern.ipc.maxsockbuf

I have found the following ctls in MAC OS X: net.inet.tcp.recvspace, net.inet.tcp.sendspace, kern.ipc.maxsockbuf

似乎recvspace + sendspace不能大于maxsockbuf. 我在这里阅读过: http://www.macgeekery.com/tips/configuration/mac_os_x_network_tuning_guide_revisited

It seems that recvspace+sendspace can't be greater than maxsockbuf. I have read about it here: http://www.macgeekery.com/tips/configuration/mac_os_x_network_tuning_guide_revisited

推荐答案

我不确定100％是否正确，但是请尝试sysctl -n net.inet.tcp.recvspace和sysctl -n net.inet.tcp.sendspace.您可以使用sysctl -w进行设置(请参见man sysctl).

I'm not 100% sure whether these are the correct ones, but try sysctl -n net.inet.tcp.recvspace and sysctl -n net.inet.tcp.sendspace. You can set them with sysctl -w (see man sysctl).
