User blog comment:SpeedySC/Does it lag?/@comment-25330335-20150203234204

Since the LOTR mod adds so much content, it basically doubles the amount of calculations Minecraft has to make per second. As the content increases, the Lag increases. Try getting fastcraft if this problem persists, it has helped many a user, including myself. However, in the future, please post things like this on one of the tech support boards instead of as a blog post, as blog posts are more seen that talked about, you will get more veiws and replies if you post on one of those boards.
