MC-Server on Raspberry Pi

[xoft]

It depends on what you want to do on the server. The best option is hosting a creative-only server, where the world generation is really not a wanted feature - instead you want to generate as little world as possible and give the players the most space for building ("flat" level style in vanilla minecraft). That can be done by configuring the world.ini to use a constant biome, flat height and possibly even same block composition, with no generated structures and no finishers. This results in the world generation being almost instantenous, and should be perfectly usably on the RasPi.
If, on the other hand, you want to host a survival server with a wilderness world, then you're out of luck, the generator will be slow and there's not so much we can do about it. You can try disabling some parts of the generator that you can do without. From my measurements on the Win platform, the generator parts ordered from the most consuming to least consuming, is this:

Code:

31 %  | trees
20 %  | wormnestcaves
7.8 % | ravines
7.2 % | ditortedvoronoi biomes
3 %   | biomal terrain composition

The rest are under 1 % each. Note that the sum gives only about 65 %, because that's the part of MCServer run time that generator eats up. Also some algorithms are not included in this roundup (no need to have two different cave algorithms); as STR_Warrior already points out, MarbleCaves are notoriously slow (about 5 times slower than any other caves algorithms); DualRidge caves are somewhere in between IMHO (not measured)

For details on configuring the world.ini, have a look at the wiki page about world.ini, which I try to keep as much up-to-date as possible:

Thanks for the makefile modification, I'll try that at home on my RasPi and see if I can squeeze some more performance out of it.
