	Have you any performance comparison with xfs?

	I'm running two imap servers. One with about 9k accounts and 3.5TB of 
storage, and another with 55k accounts and 2TB of storage with XFS, and 
I'm thinking about migrating them from XFS to ZFS but I'm concern about 
IO performance of ZFS. When we developed these two servers, I remember 
reading some zfs performance problems in comparison with xfs (I have 
lost the link) and that was the reason to finally use xfs, but now we 
are having problems with LVM snapshots and we also like some zfs 
features (like replication) so we are thinking about the change.
