There has been really bad lag in Semi-Vanilla at times lately. I do not experience it in Factions. I notice some players in Semi-V have 600+ mobs and massive automated farms and machinery - would that have this effect or is it completely unrelated? I remember once I was told that having more than 300-400 animals would be considered griefing because of the lag it causes on the server. Could someone maybe post a guide for this topic? What is OK and what is not, or at least how can we do our parts to limit the lag? In any case the lag is so bad at times that I can barely move, particularly around spawn and shops.
In this thread, cheracc talks about the guidelines for lag and being a good citizen in terms of animals and farms. http://www.sandlotminecraft.com/index.php?threads/lag-any-guidelines-for-being-a-good-citizen.19158/
