Not all 1000 mile Internet connections are equal. The 1000 miles you are talking about are as the crow flies. But an Internet rout to that same connection could be two or more times that distance and it's not guaranteed that you will get the same rout every time you make that connection. Also, if your rout has a lot of hops, it's possible for any hop to have a heavy traffic load for whatever reason. This will slow down your connection speed. The best you can do if you want to measure the speed between two points is to do an average over time.

As far as your operating system goes, the communications functions can be tweaked to maximize your connection speed for the hardware it's running on. Any machine has a hardware limit no matter what software it's running.

You are aware of more than most. But you are under the impression that a 'connection' is made like a phone call, it isn't. A single download from anywhere on the internet involves packets that take many routes to return to you. One packet may go through Chicago and the next may go through Houston. One may take a route actually going away away from you for a few states and then hop the rectangle and head your way, and the next may take a route geographically in your direction from the start.

Think of it more like a shotgun, with each pellet liable to take a far different route to get back to you, and less like a bullet headed in your direction and you get closer to the actual a nature of the internet.

What you say is true to some extent, but as soon as you establish a connection all the data packets in your communication will have a affinity for the established rout and there's a good chance they will all take the same rout. They don't have to, but most likely they will unless something interferes with that rout. That's especially true for short tests of Internet speed.

Again, you don't understand routing. You have more of a clue than most, but you are not correct. There is no 'established route', there is nothing that could even be loosely compared to that.

If you think of it more like a shotgun of completely unconnected pellets, each of which is a packet of data, that take many paths, some of which are even lost for good and have to be retransmitted, you will have a better understanding of routing. There is an IP in the header as a destination, that is handed off to the gateway of the LAN, that then makes a call based on a routing protocol like RIP(small network) or OSPF, in that second, to send it to the next network based on the routing table decision in that second. The decision may be different a second later on that same router/switch. It has no idea of where the destination of that packet is, only that is should throw it at the next gateway and let it make a call to get it closer. Then at that next hop it forwards the packet to, another completely independent decision is made by that router/switch, possibly running a different routing protocol with a different routing table, to forward the packet to the next network. None of them have any clue where the ultimate destination is, they only make a decision on the next place to forward that packet to that their table and protocol say will get it one step closer to the destination network in that second based on a criteria. Those decisions have nothing to do with geography or an overall map of the internet. Hence the packets spread out in all manner of ways when they make their way to the destination.

Pretty good. What's the speed if you pick the closest server?

So tell me why you can trace the rout with software that shows each and every hop that was used during a communication. They show you a direct sequential list of hops between point A and point B. Would they be able to do that if all the packets took off in all directions from point A to meet up again at point B?

I know about this stuff, and you don't. It was obvious you were interested, I thought you might like to know more. I was trying to help you understand things a little better, not argue.

That was a cop out answer. Also, I've been working with computers and networks much longer than you have. So quit trying to tell me what I don't know about.

They don't necessarily follow the same routes (as Dr Mabuse stated), however they 'appear' to have affinity since many route-to-route hops are more deterministic than other hops. This is because some routes may round-robin packets for distribution or offload dependent on loads, hops are often similar because network engineers have done a good job. Routes are close to optimal for each route.

Ech... Sciforums is screwing up for me, so if this is duplicated a moderator can delete the other copy.

This is because some routes may round-robin packets for distribution or offload dependent on loads, hops are often similar because network engineers have done a good job.
