Hello,

I would assume that your performance is compatible with everyday usage.

Here, an SMP machine with only src and obj subtrees in zfs is quite slow, even 
though I have a "large" 320 MB of RAM (but I'm using the straight GENERIC 
kernel, I did not remove debug-related kernel config options).

(I have mostly the same zfs-related setups in /boot/loader.conf as you)
