I know a couple of things that will help. First of all, when you first start the Tekkit launcher, go into options and change the amount of RAM usage to whatever your amount of RAM is minus 1 GB, so you don't rob the system processes of memory.

Also, in the ingame menu, change the following settings:

Graphics - fast Smooth lighting - off Fog - fast Render distance - tiny Performance - max fps View bobbing - off Advanced openGL - fast Clouds - off

These are the best settings to get maximum FPS. I hope it helps!
