It sounds like you found the issue then, which is they you set the test to 1.5Mbps which is only a small step above Dial-Up. Hard to imagine any modern website loading in a reasonable time at that speed other than of course Google's homepage. The average speed in the US is 11.5, but imagine people using Dropbox/CloudApp (a more technical demographic) would be far above that 11.5 average. Even a full Starbucks free wifi averages at least 30mbps. The lowest I've seen was 4mbps which was when I was on wifi in a cafe in Bangkok, Thailand. Comcast the largest ISP in the US for instance lowest current bundled internet package starts at 25MBps (but believe they may still have their base starter 10mbps internet only package still in some markets).
