All the extra stuff ZFS does, and does performantly, comes at a cost. That's the cost (I can't vouch for the amount.. but the principle is right. CPU power matters too.)

You don't get all those features for free... but you do get them.

While this is true, ZFSOnLinux has made progress on reducing CPU overhead. Additional improvements will be in the next release. In particular, the performance of NFS exports of ZFS datasets will increase considerably (some are seeing a factor of 2 increase) while CPU utilization has dropped:
