My Tekkit lags too. Some settings changes that could help:
 * View distance - tiny
 * Clouds - off
 * Setting the difficulty to peaceful really does reduce lag, because of the reduced spawning of mobs.

With optifine, when you hover over an option, it tells you which one is the fastest. Follow those and you should be able to reduce your lag dramatically.

I hope I could help!
