Oceania: NA or EU better connection ?
EU servers are hosted in Frankfurt, while NA servers are in Texas.
Doing a quick little ping test should give you a rough idea as to which one would be faster. Open a command prompt (Windows Key+R, type cmd and click ok, or start menu search it). In the command prompt window, do the following:
For EU, copy/paste the following line (right click the window to paste) and press enter:
ping 206.127.159.1 -n 10
For NA do:
ping 64.25.33.1 -n 10
(Change the -n 10 to however big you want your sample size to be. Something like 100 would better account for packet loss)
Whichever one has a lower average ping is better, though if they’re roughly equivalent, it won’t matter. If they are roughly equivalent, but one is more stable (less deviation), then that one is better.
To do a more general test on your internet connection, you can try http://www.pingtest.net/ and select the Texas and Frankfurt servers. Note that this will only test your general connection to that area and may not be an accurate representation of what your connection to the GW2 servers would be.
