RebelNode Posted July 9, 2012 Posted July 9, 2012 Well, the standard advice at the moment is to disable buildcraft. It can make up to even half of all resource usage and everything in buildcraft can be done with other mods like redpower. But even with buildcraft enabled you should be able to run 30 players fine with such good hardware. What do you mean with "standard server HDD"? I know many professional minecraft hosts have switched so SSDs because the reading speeds really matter much more than one would think. Some crazy people even use ramdisk (and a few of them are not all that crazy, but even succeed in it). Also, not all server virtualization software can handle java very good. Sometimes moving the server out of a virtualized environment and into the main machine can remove strange limits like it being able to use only one CPU thread. Just throwing ideas here... hope it helps... I can't really know if there exists some very specific thing in your configurations that fucks up everything else... Quote

I use only 1 CPU for some reason, how do I solve it? I can deactivate buildcraft to test... Quote
Kuckeli Posted July 9, 2012 Posted July 9, 2012 M I use only 1 CPU for some reason, how do I solve it? I can deactivate buildcraft to test... The minecraft server can only use 1 core. What kind of connection do you have? Do a speed test at http://speedtest.net/ Quote
RebelNode Posted July 10, 2012 Posted July 10, 2012 The minecraft server can only use 1 core. Ahh right, I forgot there still aren't multi-thread builds of bukkit (there are multi-thread builds of the mc-client and some other stuff). I can deactivate buildcraft to test... I think that would result in buildcraft blocks and items disappearing from your worlds upon loading the chunks they were in. Quote
