Generate world without freeze

When I generate a new world, the server freezes untill the spawn chunks of the new world are generated. How do I prevent the server from freezing?

Here's the code I use if you wonder:

Code:java

 WorldCreator c = new WorldCreator("worlds/" + worldName);
c.environment(Environment.NORMAL);
world = c.createWorld();
world.setAutoSave(false);
world.setDifficulty(Difficulty.HARD);
world.setSpawnLocation(0, 80, 0);
generateChunks(world);

The generate chunks method does not cause the problem. Infact the server stops freezing once it reaches the generateChunks method.

 

Generating a world is relatively heavy on cpu regardless of how you create it. Thats why servers can take around 30 seconds just to setup world/nether/end. Unless you boost your server performance the issue will likely persist.

The only other thing I can think of is running it in an async task (not recommended), its a possible option but not one i'd recommend. If you figure out anything let me know, i'd like to make an Rpg procedural world generator =)

 

Lorinthio You can't generate a world asynchronously. You could copy the world folder contents async but it still isn't that simple.

 

Thats what i figured =) but even then doesnt seem like there's many options for this

 

teej107 Lorinthio I've already tried all of those options. I'll sleep and I might find a solution.

 

Don't really want to mention it but... NMS? But that probably wouldnt increase performance/creation speeds
