As the title says, when I set up an instance in JapanRegion, the world loading time swells up to several times longer than the previous version.(Slowly, more than a minute)
Since the open beta, there has been talk about slow loading, but there was no adequate verification, so the bug seems to have passed with the remaining bugs.
This can be avoided for now by using US or EU mackerels, but the lag problem will make it difficult to play the game world comfortably. This is a very big problem in the Asian region.
