[img]http://static.lockergnome.com/avatars/author_988[/img]I'm spending today setting up a system for my girlfriend so she has one of her own to use while she's staying with me. I installed Windows, AVG free, Firefox, Pidgin, Office, and most recently World of Warcraft.

I discovered that while the World of Warcraft updater was running, my internet connection crawled to a near complete halt on all of my other machines on the router. It's important to note here that the download speed of the update was also extremely low, indicating that my bandwidth wasn't being used to anywhere near the capacity required to initiate a network-wide slowdown. This seemed odd, so I decided to head to my favorite bandwidth benchmarking utility to see what was happening. Here are my results for the first test:



Road Runner has done some unusual things, but giving me a 999 ping on SpeedTest.Net is certainly a new one on me. I walked over to the WoW system and gave a glance at the preferences panel on the upload utility. What I discovered was that it uses P2P in order to achieve a faster download. I unchecked the P2P option and immediately jumped over to my main computer for another test. This is the result of the second test:



I have used WoW updater in a number of instances without the slightest incident in the past, and having checked the connections and finding a reasonable 20-30 computers I was downloading from, I decided to do another test. I checked the option to initiate P2P on the uploader again and was met with the same result.

Could this be the elusive packet shaping I have been hearing about through blogs and podcasts for months if not years now? No matter what the case, I'm going to do some further testing with Azureus and uTorrent in an attempt at finding out what the root cause of the matter is.

Please leave comments below if you're experiencing simular problems, or just want to discuss packet shaping and how it is going to influence our future.
