Sorry for my bad English first.

Just like title, this is my first time play this pack, me and my friend want to try out some of the mods, we first try out the ComputerCraft in creative mode.

then when we first put the Computer from CC, it seems work out just fine, but after few minute the game will become more and more lag for example the FPS while put the Computer is about 80fps after about 10min it will drop to nearly 0fps thus become unplayable.

The werid thing is that after exit the 0fps world, i create a new world and join it, but still 0fps, Only restart the game fix the problem.
After restart and rejoin the world we place ComputerCraft, it seems no problem at all, but about 10min later, the same problem happen again.

i am not sure whether is ComputerCraft's problem or not, but i suspect there most has something wrong with the pack.

By the way, we test on singleplayer and multiplayer, we get the same result, but server seems not affect at all, only client seems to be affect to this problem

here is my log :
