I see a lot of bugfixes for my Microsoft Windows servers too, is it 
ready for production?

We use a 24 bay supermicro server with FreeBSD 9.0 and 8 300 GB sas 
drives as our NAS and ESXi backend.
We have had zero problems with it till now and it runs for more than a 
year now.
So for us it works very well.
The ESXi clients connect to the server through NFS
The windows client store there profiles and home dirs on the server with 
samba
We have two ESXi hypervisors each running 5 servers and a couple of 
workstations.

We do not use any tuning beside one loader.conf setting where we set a 
max to the arc to about 3/4 of the available memory.
The box has 16 GB of ram
So for this machine we use the following.
vfs.zfs.arc_max="12G"
