1.  What mailbox format are you using?  Is this a constant or variable?

Maildir++

2.  Is the Dovecot rev and config the same everywhere, before/after?
Yes
3.  Are Dovecot instances using NFS to access the XFS volumes?
NO. direct LVM volumes from SAN
4.  Is this a  Dovecot 2.x cluster with director and NFS storage?

NO. This is dovecot plain & simple.

When I go back to older kernels, the load go down. With newer kernel, all is working well too, but load (as reported by uptime) is higher.

Thanks,
