this kind of system well. From newfs(8) the min block size is 4k. This
is not optimal in our case, a 1k or 0,5k block is more effective IMHO.

I have tried using a 4K/0.5K UFS1 filesystem in the past and found the
performance was very poor. UFS2 was based on 16K/2K and I would expect
it to perform even worse with 4K/0.5K. I would suggest you try 8K/1K.
not for small files. you are light with large files but it's not THAT bad

Zfs has send/receive where you can do snapshots and send them to a
different host.
snapshot of a partition, in order to perform a background-fsck and
thus our website was down. So ufs2 does not scale well.
Reasons not related to the nfs-server itself. FreeBSD itself was
rock-solid. It was firmware-related on the storage-side.

Short answer: No.
Longer answer: FreeBSD and UFS2 have
