This is the only good creative tekkit lite server I can find, and I'm glad you work so hard to make it better. One thing though… LAG. This is probably the laggiest server I know of, and I'm not complaining about it, instead, I want to help you fix it. First of all, the ClearLag plugin only removes certain types of entities. Dropped items, xp, etc… I think you should configure it to remove ALL entities. I think that would help out a lot. Second, ban ALL the different types of chunk loaders (if you haven't already). Third, look at which areas are having more chunk updates than others to find and remove lag machines. I hope these ideas help remove at least some of the lag on this server. Good luck!
PS. I would appreciate it if you would ban alarms too. Those things are annoying as hell.
