I don't understand why you'd have a bad performance here. I usually
notice a very slight difference between LVM and linux-raid raid0 in all
practical benchmarks. Did you use LVM striping capability? You may
have to adjust readahead (using blockdev --setra) on each
device /dev/dm-X and /dev/md-X) to achieve optimal performance.
