That’s the mother of the lamb, we use to say in Spain ;)

I guess it depends on the particular distribution, not just on being ext4. Is there a tool similar to
dumpfs on Linux? 

You can also experiment with the FreeBSD options, maybe it will be a quicker route. Try to mount as asynchronous.
In case it  makes a big difference, you got it.
