Nostalrius Begins - Quality wow vanilla realm (1.12)

PERFORMANCE AND LAGS:
During this week, we applied a second bunch of fixes to reduce the lag / delay, after the dynamic lag reduction system last week.
We also implemented an index to know how our players feel the lag. The lower it is, the less our players feel the lag. It was around 500 at the beginning of the week, and it has been lowered thanks to the different fixes to less than 400 (ie 20% lag reduction, for a similar number of online players). Note that this index also counts client connection lags, not related to the server.

How does it work ?
Several strategies have been implemented.
First, we assigned different priorities to the different tasks the server has to do:
Spells and movement server: top priority
Chat server: medium priority
Creatures/pets AI: medium priority
Items/AH server: low priority
Characters loading and mail server: lowest priority
It means that you may experience a delay when sending mails, looting items, ... But it is only to allow a real-time handling of the spells, our top priority. So do not rely on the chat to test if the server lags for example

Our second strategy is to define a priority between the players. Someone being in combat, casting spells, or in a dungeon / battleground will have a higher priority than a player that is AFK in a capital, playing with the AH, or simply chatting.

We continue monitoring the server performance and are still exploring new ways to make the game experience the most enjoyable as possible.
