Hello,

My name's Jerome ROUSSEL ; I play on Minecraft 1.7.9 on a private server of minecraft running on the same PC. A friend which play on an other PC throw internet (connected in my server) had the same problem in the same position.

The client lag in a specific position of my Map (around x=-185 y=11 z=45).
When Iquit this zone, no lag.

FPS 60 to 0-5 in this area.

Server don't print any message but the minecraft client std out print : "[HH:MM:SS INFO]: Client> [HH:MM:SS] [Client thread/INFO]: Warning: Clientside chunk ticking took # ms" with # around 1000 ms.

Steps to Reproduce:
1. Just go from P1 (x=-156 y=15 z=34) to P2 (x=-186 y=11 z=47)
2. Turn around and go away with a lot of lag until P1 (lag go away)

Thank you in advance.

Jerome ROUSSEL
