Is anyone aware of any freeware program that can speed up copying tons

I use 'ufsdump | ufsrestore'*. I would also suggest try setting
'sync=disabled' during the operation, and reverting it afterwards.
Certainly, fastfs (a similar although more dangerous option for ufs)
makes ufs to ufs copying significantly faster.
*ufsrestore works fine on ZFS filesystems (although I haven't tried it
with any POSIX ACLs on the original ufs filesystem, which would probably
simply get lost).
star -copy -no-fsync .... is typically 30% faster that ufsdump | ufsrestore.
Does it preserve ACLs?
