Have a look to the right & does it tell you the Vendor of the person you're downldg from. Then most reknown for being slow are RAZA (Shareaza) who often seem to offer around 0.1 up to 2-3 KB/s. lol (OH by the way if you don't have the vendor column you can choose to show it by right-clicking the very top of the downld columns. A menu will appear & just select vendor/version. This will show which p2p share client you're downlding from.)
