I know this may have been stated somewhere here but I couldn't find the forum searching for it. So I have a 64bit server that uses a 6 core processor. So, I found out recently that java is only using one of my cores and the other 5 are not even touched. This to me is crazy as I am paying for so much power but MC can only utilize 1/6th of the processing capabilities of my server. I read this forum post about putting flags to add garbage collection but still only uses one core: http://www.minecraftforum.net/topic/63836-making-your-server-lag-less-by-tuning-java-settings Is there a workaround for this? Is there a way to make java multi-threaded? Actually this is more meant for the bukkit help forum, whoops EDIT by Moderator: merged posts, please use the edit button instead of double posting.
