Ever sense the release of 1.6.4 my server has been experiencing constant minor server lag all the time, and major server lag after world save. Server runs an average of 17tps, and after world save can drop down to as low as 7tps. I was hoping that this was an issue caused by 1.6.4, and would disappear after updating to 1.7. I know that the 1.7 versions are dev builds, but I am starting to wonder if this issues is really something local and not something caused by 1.6.4. So I am asking around trying to figure out if I am alone here. Did anyone else see this mystery lag pop up after updating to 1.6.4?
