ive just been testing transfer speeds using the 1.3 wallet and sadly it is very slow even using my 300meg connection, (i uploaded about 2 gig of lo res photos to test). I think this will get better as the wallet is developed and am currently a host myself making a menial amount of coins per week but im glad to be helping the network and look forward to the future! (my current Sia stash is 80,000SC - Hodl like crazy)
