MAX_EVENTQUEUE and Server Optimization

[spangler]

Hi guys! I had several question regarding eventqueue and its impact to server performance.

1. By default MAX_EVENTQUEUE is set on 2, I was wondering how big is the optimum value EVENTQUEUE can actually hold?

2. If you increase the value of EVENTQUEUE setting, will it impact server performance? )such as lag, memory, etc)

3. How to optimize server performance to accommodate 500+ people? In which part of sources or script can I optimized this

From what i understand, it's optimum value is 2. I personally have set mine to 20 as i have a lot of OnPCLoginEvent scripts which would ordinarily exceed the queue value.

There's no magic settings to "optimize performance". The more scripts you run on a server, the more resources it will use. The more players you have connected, the more scripts you have running.

The best answer i can give you for number 3 though, is to avoid scripts that use timers/loops. Scripts that use static data perform better than scripts that use dynamic data. Keep your variable usage to a minimum by using bitmasked values. Event scripts that spawn x amount of monsters in a specific location at x times of the day are discouraged, as that will create your resource bottlenecks.. but if you know where they are, then you can do things to combat them

Thanks that really do answers a lot!

Wow didn't expect bottlenecks on that kind of monster spawn script though, can't say true enough, now I do know where should I optimize my server script.

If anyone can have different opinion or fact , you are welcome to reply.

It's not because it's a monster script, it's because it's spawning monsters to a map and most likely all have attached scripts and a timer. It can cause small amounts of network latency and increases the ram and cpu usage of the map server. It's not a big issue by any stretch, it's just something to remember when creating scripts for high population servers.
