Huh, that's twice as fast as mine...
Yeah, while Impulse my download speeds can reach around 150 - 160kbs, (occasionally a little higher) they're most often around 90 - 100kbs.
However, I put that down to having a second, sometimes third PC online using bandwidth... and sometimes my ISP. There are times of the day/night when connections are noticably slower due to larger numbers on-line... eg, shortly after schools get out and early evenings when workers get home. Later at night and the early hours of the morning is usually the fastest, when more people are off-line and in bed.
So slow downs may not be down to just the Stardock servers.
