推荐答案

本<打击>非常丑陋的黑客其中的也许的给你一个更快的下载时间，也可能是不，你有你的条件下进行测试：

This very ugly hack which might give you a faster download time, or maybe it doesn't, you'll have to test it under your conditions:

开始几个平行连接（在单独的线程），并且每一个应该下载不同的组块数据的（使用的 HTTP 1.1 Range头）。这取决于很多事情一样，如果有一个满月，或太阳出来或玫瑰绽放，你可能会得到更好的效果，因为它会饱和你的链接比单一连接（每个人的牺牲更好别人分享你的链接，有点像BitTorrent的是什么呢）。

Start several parallel connections (in separate threads?), and each one should download a different chunk of data (using HTTP 1.1 Range header). Depending on many things like if there's a full moon, or the sun is out or the roses are blooming you might get better results because it will saturate your link better than a single connection (to the expense of everyone else sharing your link, kinda like what BitTorrent does).
