From what I've read, it should be faster on a machine with 2GB RAM and 
10TB storage, while it's maybe slower on a 64GB RAM machine with a 1TB 
xfs storage. Given that disks grow faster than RAM sizes, and that with 
virtualization a single machine typically has not too much RAM these 
days, I guess with the patches speed will improve overall.
