Does bukkit support multicore?

I have a single core computer, windows 7 64bit 4gb ram and it averagely sits at about 100% CPU usage, looking at getting a new one with multiple cores but I heard something about bukkit not supporting multiple cores..suggestions?

 

It supports Multi Core. I have a Dual Core Procesor and it works fine, I just have a few probs importig from singleplayer (not to do w/ bukkit itself) and it works fine. however i do not know if It supports thinks like quad core prcessors

 

Bukkit itself does not support multithread (Main part is chunk loading and thats still a bit slow but theyre working on it). Much pluins support Multithread.

It works fine for me does not mean that it is multicore!

 

Well, I kinda assumed seeming as I have a dual core,
and my Friends Gaming PC has dual core, and it works just fine. Sorry for the assumption

 

Minecraft is single-core though .. I possibly see using Multi-cores have any benefit. Most people recommend disabling Hyper threading .

 

Just like most people recommend disabling swap. But as always, most people know nothing about computers, so don't listen to them

 

So you are saying that leaving hyper-threading on is no different in performance, than if it was left on?

 

Minecraft isn't optimized to take advantage of multithreaded processors. All applications can run fine on a multithreaded processor, but it doesn't mean they use more than one thread if they weren't designed to. Although, Java does allow use of multithreads for some of its garbage collection settings using Java flags, and this can help slightly with performance, since the game uses Java.

 

So what I am understanding is if i have multicore I should set it up to only use one?

 

Disabling hyper threading lowers the overall performance of a processor. Even if you have only one thread of minecraft, what about all those processes in your OS?

The same goes for multicore processors, yes minecraft will use only one, but it still leaves one aside for other stuff, so it helps (not much but it does help).

Pinning minecraft to one processor only also does not help because it does not mean that only minecraft will run there, it will still share it with other processes.

 

Bravo good sir! Bravo
