Hello, i'm running some small server (10 people max, but i don't have problem rising limit) for people who like to enjoy (almost) worry free server that include latest tick threading for ultimate server experience, in short tick threading can run every 16x16 area in separate thread, so far i haven't seen many problems.
If anyone is interested in building in small community (me and my friend currently heh).
You can check it out at http://cpy.zapto.org
To play you'll need at least set javaw -Xmx2G -jar (quite lot mods, will work on default settings but 2G is better)
