I have a raid controller with BBU and I would like to optimize zfs for
I have already put away hardware raid and I use software raidz.
Now I would like to optimize writes considering that the 256mb ram on
the controller are persistent.
On solaris zfs they suggests to disable flush can I do it on linux?
What else can I do? Make sync=always?

Thanks in advance for any help,
