Hey guys, I would like to know what your favourite anti-lag plugin is and why. I've been on servers where they have a plugin that regularly removes mobs/drops to get rid of lag, and I would like something like that.
This does close to what you want: http://dev.bukkit.org/server-mods/nolagg/ Everything is configurable.
For simple removal of mobs/dropped items, you could try "lagclean" or some other similar plugins. They are quite effective.
I've seen from several threads now that nolagg is actually causing lag with the newer versions of bukkit...
I'd rather make sure that all other plugins are configured properly to suit your server needs, player count and CPU/RAM/Bandwidth power, before throwing another plugin in there hoping it will do some magic tricks. For example, DynMap is a plugin you can configure in a way that it runs fast and doesn't cause too much strain on the CPU and I/O, but you can also easily configure it to eat CPU like there were no tomorrow. Same goes for a number of other plugins.
