64 bit processes can take up to twice as much RAM as a 32 bit process, but not all do. It depends on the application and what data its using. The only way to know is to try it. answered 05 Mar '12, 17:14 johns Thank you. I wish to take advantage of the cgroups functionality without the cost of high memory usage.

You say the only way to know is "to try it". Are you able to migrate back if you're not happy with the results?

Yes, we can revert the migration if you're not happy with the result. That must be done within a week of the migration date - we delete the data from the old server after that date.
