Although Xunlei offers a satisfactory download speed, its over-enthusiastic service has caused some minor troubles. When we click on a link, the IE download box will pop up, and at the same time, Xunlei will also启动"self-initiate" unnecessarily. For users with not-so-high machine configurations, they have to endure the system slowness caused by Xunlei, especially for small files of a few hundred KB or MB, the time it takes to download using IE might be shorter than the time it takes for Xunlei to start.
