Some downloads are slow
 

i dont know why , but some downloads with speed t3 or higher come fast at 140 kbps - ( my max speed on my computer ) but some downlaods of the same t3 or higher speed dont go above 20-40 kbps .

What speed should i choose, t3 or higher, t1 or broadband, or is it that the speed will increase if i choose a file which has more than 5 - 7 hosts

what are the other parameters on limewire , or ideas you may suggest so that i get the maximum download speed

It very much depends on what hosts you end up connected to, you may have the maximum number of hosts for a file and end up with a slower download speed this can be caused by various reasons...ie. firewalls etc...

This sticky will give you some tips on how to maximise your downloading...
