DMIT VPS 单线程调优TCP测速突破200Mb 实战经验（实测其他Vps同样有效果）

200主要是本地运营商限制吧，美西230左右单线程极限了
各家我都测过 上限一样的。

首先帮顶= = 其次有没有可能是我当地联通到美国单线程锁死200 就是我其他鸡随便单线程好几百 就dmit永远200 是不是本身网络就有问题

顶一下，好贴

拿瓦子试了一下 真的有效 没改前 单线程220
改完 单线程480

openwrt能玩吗

谢谢分享，待会回去试试

你的结论和我之前试的一样的！有空你按我的方法在试试，我还是在广西测试的，如果在上海只会更快！

@ko1t0 #10 什么叫参考几何，测出来多少就是多少呗，难道虚标不准？我就是后端主，跑多少速率我本地看得到

如何修改为永久有效
我也是问 AI 的，Macos 的修改方法

新建 plist 文件

sudo nano /Library/LaunchDaemons/tcp-bufsize.plist

粘贴以下内容（原样）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
 "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>tcp.bufsize.tuning</string>

    <key>ProgramArguments</key>
    <array>
        <string>/usr/sbin/sysctl</string>
        <string>-w</string>
        <string>net.inet.tcp.autorcvbufmax=16777216</string>
        <string>net.inet.tcp.autosndbufmax=16777216</string>
    </array>

    <key>RunAtLoad</key>
    <true/>
</dict>
</plist>

修正权限（非常关键）

sudo chown root:wheel /Library/LaunchDaemons/tcp-bufsize.plist
sudo chmod 644 /Library/LaunchDaemons/tcp-bufsize.plist

立即加载（无需重启）

sudo launchctl load /Library/LaunchDaemons/tcp-bufsize.plist

验证是否生效

sysctl net.inet.tcp.autorcvbufmax
sysctl net.inet.tcp.autosndbufmax

应该看到：

net.inet.tcp.autorcvbufmax: 16777216
net.inet.tcp.autosndbufmax: 16777216
