What you'll need to do is steps. Just doing one step will make it run faster, but doing all of them is recommended.
- Set your mode to Fast and render distance to Tiny.
- Open Windows Task Manager (ALT+CTRL+DEL) and set javaw.exe priority to high.
- Set your battery options to High Performance.
- Download GameBooster and hit the "Boost" option.
By this time, Minecraft should be running almost perfectly.
