I run my server through NFO. I myself just downloaded a 100mb installer from another site at 1.8 mb/s.
If there is some configuration I have to change do you know where it is at?
I don't know on that one, no. It would depend on the software.
I tested from Dallas and got 2.0 MB/sec, which is still lower than I would expect between these location, but an order of magnitude faster than what I'm personally getting from my home connection. Hmm.
I am however, with rogers internet. But like I said I have fine download speeds.
Unfortunately it isn't always the case that the whole internet would seem fast or slow. It is possible that Rogers, or a NSP between you and us, is having a problem or doing something unusual that would cause an issue like this for you with only certain destinations.
I will have to work on setting up another VDS in Chicago with Apache, on a different physical machine, to use for comparison. Your situation is definitely unusual and I am very curious as to what is going on beneath the surface here with the routing.
