hi guys, wanna ask anyone experienced such thing b4 or not

usually when i download stuff from mediafire, i can get fullspeed with flashget, but recently(bout 2 days ago), the task will start with fullspeed, then slowly reduce to 10kbps, then will be quite constant around that.

At 1st i thought might be mediafire only, then i go download some other stuff which hosted on their own server, also facing the same thing.

But the weird part is, my xunlei download can go fullspeed.
