Improve FPS on minecraft due insufficient graphics?

I want to find a way to improve the FPS of my minecraft game. Specifically technic pack.

my specs are:
Dell inspiron 15R
CPU: i5 2nd gen 2.6 GHZ
Graphics: Intell HD Graphics
Memory: 4gb

i'm sure that my memory and CPU are sufficient enough. However i suspect that my graphics is the probelm. Any ways to up the FPS other than lowering the video setting (already lowest).

The combination of these helped me immensely as my laptop is not the greatest. All 3 mods are fairly simple to install. There's OptiFine, OptiLeaves, and FpsPlus. And also I would suggest allocating 2gb+ ram to Minecraft. In the Minecraft Launcher, to allocate memory or add start-up parameters, start the launcher, and click the Edit Profile button. Look for JVM Arguments under Java Settings and add what's needed there.
