I am on cable and I can download just fine with LimeWire, I love it.

However, when someone tries to download from me, it will start the upload but always so slow... 2kb/sec and down.
But when I upload a file to someone, say, over FTP it usualy goes around 80kb/sec, depending on their connection speed...blahblah u know the deed...

But on LimeWire, its just ack...
I also have had this problem on WinMX.

Anyone know what causes this?
