百度云加速器 - baiduyun-accelerator

随着百度云限速的到来，速度已经降到100KB/s以内，每次下载都很烦恼；该工具是为了解决此痛点而生。该工具使用了HTTP RANGE原理进行分段下载，可以将一个文件分成N块来下载，这样下载速度就有可能提升N倍（理论上）

使用

下载baiduyun-accelerator至本地: https://github.com/smallmuou/baiduyun-accelerator

/bin/bash baiduyun-accelerator redirection-url [split-number]redirection-url是重定向的下载地址，可以在浏览器中点击下载，在下载队列 - 详情中找到Redirection；注意该地址会在一段时间后过期split-number是分块的数目，默认10个；理论上配置越大越好，但要考虑时间CPU、文件大小、带宽；因此配置越大，下载速度并不一定越大，具体可以在实际网络中测试。

对比结果
