Use something other than Open/Solaris with ZFS as an NFS server? :)
I don't think you'll find the performance you paid for with ZFS and
Solaris at this time. I've been trying to more than a year, and
watching dozens, if not hundreds of threads.
Getting half-ways decent performance from NFS and ZFS is impossible
unless you disable the ZIL.
Well, for lots of environments disabling ZIL is perfectly acceptable.
And frankly the reason you get better performance out of the box on
Linux as NFS server is that it actually behaves like with disabled ZIL -
so disabling ZIL on ZFS for NFS shares is no worse than using Linux here
or any other OS which behaves in the same manner. Actually it makes it
better as even if ZIL is disabled ZFS filesystem is always consisten on
a disk and you still get all the other benefits from ZFS.
What would be useful though is to be able to easily disable ZIL per
dataset instead of OS wide switch.
This feature has already been coded and tested and awaits a formal
process to be completed in order to get integrated. Should be rather
sooner than later.
You'd be better off getting NetApp
Well, spend some extra money on a really fast NVRAM solution for ZIL and
you will get much faster ZFS environment than NetApp and still you will
spend much less money. Not to mention all the extra flexibity compared
to NetApp.
