Sorry, I was downloading porn. 555 j/k
It just depends on when people are downloading. More people less bandwidth to share with everyone.
You answered the question that it isn't your connection. The best you can do is to tell everyone on SW to stop downloading the lakorns so that you can download them.
Or hopefully, people will upload to several different sites and allow various users who watch your lakorn options to dl and not fight over the same file and make it slow.
All I can say is, I haven't watched a lakorn for a year... so itz not me. 555
