【原创调优脚本】Tcpfit — 单线程 186 → 401 Mbps，动态 TCP 调优，优化线路机器通用一键开源脚本

确认

      带宽           1000 Mbps        整形安全余量 25 Mbit
      整形           实测拐点后自动决定
      对端           speedtest.hkg12.hk.leaseweb.net:5205
      用途           代理 / 加速
      iperf3         3.18
      安装位置       /usr/local/bin/tcpfit

      预计耗时       约 10 分钟
      预计流量       约 29.0 GB
                     先测一档判断有没有限速器, 没有就到此为止

  [2/5] Path quality check
[*] Probing at 40% of 1000 Mbps -- far below any policer.
    Retransmits at this rate would mean the link itself is lossy.

dd报错了

希望能支持prompt模式。

示例:
Command: npx skills add https://github.com/vercel-labs/skills --skill find-skills

Prompt: Run npx skills use "https://github.com/vercel-labs/skills" --skill "find-skills" and follow the generated skill instructions now. Read its complete output, redirecting it to a temporary file first if necessary. Resolve relative paths from the supporting-files directory it provides.

megabox 测了下说是没有整型的必要，超过 1000Mbps 了

⠏ 测速中… 10s × 4 流 → speedtest.lax12.us.leaseweb.net:520/usr/local/bin/tcpfit: line 1738: margin: unbound variable

收藏一波

配置低的小鸡难搞啊，内存不够之后512,硬盘1G都不剩。

收藏了

这和codex直接调的有什么区别？

最后一部报错，有人成功过吗
