The Game lags too often in 16w15b.

Summary: After 16w15b was released, I have been experiencing too much lag for it to be normal. The way the game lags is by making regular lag spikes as shown in the debug screen. Not sure if this is a duplicate or invalid, cannot seem to attribute the cause of the issue as of now.

Game Output:
