I have a similiar system to the one described by Iron Man and it works fine for me. I've bee using XoloX for 2 weeks and have 1.2 version etc. but for me I noticed the reson why downloads may be slow is because of time zone, I'm 8 hours ahead of GMT and have noticed that I get more downloads when I log on at certain times such that I catch more users who may be online at night. I think as the Xolox user base continues to grow this will cease to be a problem. I have also noticed the mp3's I'm trying to download usually are low hits because the music I'm looking for is less mainstream so I usually must wait longer until I that user comes online before I get it. I also find that setting my upload speed to the max is better because it allow people to dowload the music from me quicker thus allowing the file to be used and passed on by more members.

Just thought I would share my humble experience and thoughts so far with other users thus far.
