Upload inconsistency
 

I have Limewire 4.14.10 and am somewhat confused by the number of uploads I am getting. One day I will get around 150-200 uploads in a couple of hours, and the next I will receive virtually no uploads at all. I have no firewall and a fast internet connection, and am using limewire from home, on a laptop which is permanently connected to the broadband connection. These never change in any way from day to day. Does somebody know why the number of uploads changes for me day to day?
