How do I make Minecraft run faster?

I use a Thinkware laptop and it lags like no other, it's unbearable, way too much lag to even move carefully so I can't even play on Peaceful! Is there any way I can make my computer run Minecraft better? I mean, it runs games like Civilization IV and Oblivion with practically no lag, so I have no idea what's going on. Please help!

Answers:

Maybe you could try this 1. Go to Control Panel 2. Find the JAVA icon, and click on it 3. Java Control Panel will open and you'll find 5 or more tabs, select Java tab 4.- Push the "View..." button for Configure Java Runtime Environment. 5 .- Here is the trick, java uses only 256 mb of memory for his own purposes, and Minecraft needs more than that. See how much ram you have and increase java's memory usage as this: Guru's says that you can let java use the third of your total installed memory, for me its easy as I only have 3gb of installed ram on my computer, so i'm gonna let java deal with 1024 mb of ram (1 Gig) how? add this command in your Runtime Parameters on each entry that you have in this list. -Xmx1024m as shown above no spaces with the minus symbol at the beginning and an "m" at the end. in the above example, 1024 is the amount of memory that java will use, you can try 512 for small machines or 2048 for big ones.
