This project has been discontinued. TickThreading is not 100% stable. Please make sure to keep regular backups if you use it. Make sure to check the mod compatibility list on the wiki before installation. 1.6.4 Testing build: latest very unstable 1.4.7 Stable build: latest 1.5.2 Discontinued build: latest What it does: * Ticks multiple worlds at the same time in different threads * Ticks multiple entities and tile entities within worlds at the same time in different threads * Performs movement updates in network threads, so players will move smoothly even if TPS is bad * Adds profiling tools which allow you to find what's being slow * Performs chunk loading and chunk generation asynchronously - no lag spikes from players logging in or teleporting * Replacement mob spawning algorithm which is faster than in vanilla, while also fixing a long-standing bug causing mobs from to spawn underground too much during the day preventing any spawning at night * Improved collision code which can handle thousands of mobs in a single block space without terrible TPS. Will still break clients. * Many more small tweaks to minecraft's internals and other mods, both to improve performance and ensure that multithreading doesn't break everything. Installation guide: https://github.com/nallar/TickThreading/blob/master/INSTALL.md Will this magically fix everything and make your TPS 20 with no CPU load? No. It should improve TPS, but I can give no guarantees. If performance is terrible, follow the guide on the wiki to record a profiling snapshot with jvisualvm so I can fix it. Commands: See the wiki. What to do when everything breaks: Make an issue here, paste logs to http://gist.github.com/, pastie or pastebin. Make sure to give the full log - there's not much I can do if you only give me part of the problem!
