Regarding Server/Lag Issues | 11/14/2004 5:21:27 PM PST | WoW Gameplay Discussion


Hi all,

A number of inquiries have come in about the lag issues on some of the servers, so we want to take some time to provide more in-depth information for you. Some of you might be surprised to learn that the lag you’re experiencing is an expected and necessary part of the open beta test. Contrary to what some of you might believe, the open beta test is intended as a massive stress test, and not just a free demo of the game prior to launch.

Having hundreds of thousands of testers playing the game at this time lets us analyze how well our server infrastructure -- made up of the best, most up-to-date hardware available -- can handle extremely large server populations. In fact, the open beta test is allowing us to simulate having an even greater number of testers spread across even more servers than we currently have up. In terms of concurrency, we’re already seeing servers with twice as much population as we had during the closed beta test, and our total overall concurrency, across all servers, is already rivaling that of the most popular MMORPGs currently available. Keep in mind, also, that this population is distributed across a relatively small number of servers -- again, for the exact purpose of stress testing them.

In general, lag issues are caused when thousands of players congregate in one or two zones on a server. When this happens, the normal communication that comes from the server -- which includes information about every NPC, monster, player, item, etc. in the area -- increases to the point where the flow of data can get backed up.

For those of you who are concerned about server stability and possible loss of character-related information, take heart knowing that the lag you experience when this backup happens is not at all related to stability; it’s more of an issue with how quickly the data is handled. That is, with an excess of communication from the servers, the data remains stable, it just has to wait its turn in line to be processed. Running a massive open beta test like this allows us to steadily optimize how the data is processed.

With half a million people having signed up and been accepted into the open beta test, we have the unique opportunity of being able to fine tune our code prior to release in a way that most other MMORPGs have not. These code optimizations are done server side and do not require players to patch. As more and more testers finish their beta-client installations and start logging on, we’ll be able to do even more analysis and optimization prior to release. While this process brings about a challenge for those of you facing lag issues, it ultimately helps us maintain our schedule of analyzing and optimizing our code for all of our servers, including the ones that have yet to be brought online.

We are looking forward to having hundreds of thousands of players enter the world of Azeroth on November 23, and we‘re grateful that you all have the interest and the patience to help us do this last, sometimes challenging, bit of testing. Your assistance with this will truly help us ensure that World of Warcraft will run as smoothly as possible at launch.

鉴于多数人对E文没有兴趣看完，简单介绍一下内容：
现在的Lag是因为我们正在测试服务器性能，记住，现在每个服务器上的人数大约是以前Close Beta的2倍，如此大量的用户可以让我们更好的测试服务器性能，并为优化核心代码提供数据和依据。Lag主要因为大量的玩家集中在少数的几个区域造成的（言下之意，你跑到人迹罕至的地方去，应该就不会Lag了）。而且数据方面大家不用担心，备份工作和系统运行得非常良好。大家不必为服务器的稳定性和可靠性担心。
最后请记住，现在是Beta测试，请忍耐这一切，并尽量支持我们的工作，这些都是为了23号正式发售能让成千上万的人有一个完美的体验，我们将感谢大家为此所作出的共同努力。

另外，官网上还有一些介绍如何避免或减少Lag的民间帖子，大致上说，当你第一次捡起某个可以堆叠的物品时，会Lag，但是第二次捡起的时候就不会了，分析可能是要创建这个物品会排队排很久……有兴趣的可以到官网上搜索"Lag"
