If you're talking about fps you could try turning the render distance down in the settings. Along with changing the graphics from "fancy" to "fast", and other things. google is a great place to find that out.
Install optifine, then go into video settings and turn everything to it's lowest possible level. (Turn off smooth lighting, turn off mipmap, turn off anti-aliasing, turn off particles, put render distance to tiny, put the graphics to fast, etc...) If that does not help then you may just need to upgrade to a better computer.
