Open "Notepad"

Copy and paste either 1 of the code into the "Notepad".
Example:javaw -Xmx512m -Xms512m -jar Minecraft.exe

Make sure you choose a ram that is not over your computer ram. For example i have a 4GB RAM Computer, please do not use a 4GB code. Reccommend going for 1GB or 2GB would be good. For better performance use 4GB

Save the "Notepad" and change the .txt to .bat. If you do not have a .txt at the back just add .bat.
Example: ImproveSpeed.bat

Now place the .bat file at the same directory as your minecraft.
Example: my minecraft is in games folder on desktop, so you place the .bat file that you created into your games folder on desktop too.

Run the .bat file that you had just created and login to minecraft to play!
