Here is a full log from me loading my creative world and then closing: I tried seeing if removing some of the Java instructions (-xx and useg1gc) would change anything and it didn't seem to help in anyway. Increasing the minimum memory from 2 to 4 while leaving the max at 4 did seem to help in chunk loading but NPCs were still lagged and placing new ones with eggs was also lagged.

I should clarify that by lag spikes, I mean that, aside from breaking blocks, I can not interact with anything, and npc/mobs stop moving briefly, before rapidly moving where they mean to be. During these spikes I can still move freely.

Additionally, I attempted to roll back a few snapshots and still had this issue. Attempting to create a new 1.7.10 world resulted in this:
