Need more information, but I'm guessing turning your IC2 and/or Advanced Machines sounds off will probably help. That's in IC2.cfg and AdvancedMachines.cfg, both in the .techniclauncher\tekkit\config folder.

I've wondered for a while, what is it about the sounds that makes it lag? Turning them off does help with a lot of the lag in most circumstances, especially when there are a lot of sources for sounds.
