Well disabling zil may bring you better performance but at the price of data
integrity.
Check this blog entry (which was referred to in the link I gave you before) for
details: http://blogs.sun.com/roch/entry/nfs_and_zfs_a_fine
A seperate SSD zil device may be a more expensive but proper option.
Thanks for the info. In the meantime I got the tip from the mailing list to try
zil_disable. This brings good performance. Next we will try to reinstall
OpenSolaris with raid-z2 instead of Hardware Raid 6. Hopefully this solves the
issue. Otherwise a separate ZIL device sounds like a good optio
I have not checked if they are the same issue but you might want to check this
out:

A seperate ZIL log device (such as SSDs) might help to boost the performance.
