If you're getting substantially better performance with LVM than with 
ZFS then you've done something wrong. ZFS done right is only a little 
worse than bare disk speeds assuming that you have enough physical RAM 
for I/O cache (or dedicated ZIL and L2ARC vdevs for heavy I/O loads) and 
enough CPU for raidz, compression and encryption if you are using these 
features.
