Yes, but you`re talking about 6.7 gb. Let`s round it up to 7, 8 gb of ram isn`t going to be enough and I was going to say 16 gb will be a lot more expensive but after checking out newegg I see G.SKILL 4GB 240-Pin DDR2 at ~100$ which is not that much afterall.
8gb (4x2gb) ~100$, 12gb ~250$(2x4+2x2), 16gb ~400$.
I`m assuming here that most of us are still on DDR2 with a 4 dimm motherboard and support up to 16gb of ram.

Lowerping seems to be targeted at an Oceanic audience that wants lower-latency connections to Blizzard data centers located in the US. If the trans-Pacific link used by a particular Oceanic ISP is congested or has other chronic issues, and lowerping has access to a link that doesn't suffer from those issues, then a WoW player could feasibly see an improvement by using their service. In effect, the user would basically be changing to a different ISP for the purpose of a single game.

The propagation speed of an electrical or optical signal along any cable is fundamentally limited by the speed of light, so any user in Australia is going to get a few hundred milliseconds of lag to a computer in the United States regardless of any tweaks or improvements. That's just basic physics. The propaganda on their web site talks about 600+ ms ping times reduced to 300-ish milliseconds, which seems generally feasible if you trade a bad connection for a decent one.

This was covered in a thread quite a while ago - see http://elitistjerks.com/728397-post271.html. I think there was some discussion in that thread about people in the US reducing their latency slightly using it (dropping 50ms maybe?).

A little nitpicky, but the limits of the relevant telecommunications tech are not primarily caused by the speed of light. Light travels 90 000 km in 300 milliseconds, which is obviously a lot further than the distance from Irvine, CA to Australia.

For people concerned about their latency, be careful about using tracert / traceroute as a ping utility, because it really isn't. Windows (from NT at least) have a built in command specifically for this, called pathping. This combines the tracert and ping commands to give a much better view of your actual latency through your network.

Use the command "netstat -n -p tcp -b | more" to find the ip you are connecting to. Somewhere within Blizzards network you will not be able to get ICMP echo requests, since they understandably don't support this on the actual servers. But if your routing and ping is fine up til that point, it's fairly reasonable to assume it's not a routing issue.

Correct, and newegg is where i shop as well. I have only 4gb now but looking to go to 12gb with a 8gb ramdrive; with the actual memory you linked. I really have high hopes for this making a big difference in game play once i get the .mpq files in there.

I don't have SLI, but I do have the ATI equivalent - crossfire. I disabled crossfire about a week ago after reading this post and my PC hasn't hardlocked since.

Nitpicking your nitpicking of a nitpick:

All of what you said is largely true about net speeds, but specifically light never slows down. It appears to slow down when it interacts with mass because it is absorbed and re-emitted by the atoms of the material. But between atoms its still traveling the full speed. So the potential is still highest with raw light.

Australians have reported huge boosts by it on World of Ming:

For further refrence!

You are not alone - I don't see how this could be achieved, either, unless your link to Blizzard's data center is really terrible. Tunneling anything through an SSH connection will hurt roundtrip times badly. If they were offering an unencrypted PPTP connection, or a GRE IP tunnel, things would be different. But with SSH, I think you will only see an improvement if your connection is terrible.

Almost all Void Zone type things in the game are visible at the lowest Spell Detail. In fact it helps to pick them out from the DK/Paladin crap that is all over the ground. It can make things like the Blizzard on Sapph a bit harder to pick up though.
