I have a couple of performance questions.
Right now, I am transferring about 200GB of data via NFS to my new Solaris
server. I started this YESTERDAY. When writing to my ZFS pool via NFS, I
notice what I believe to be slow write speeds. My client hosts vary between
a MacBook Pro running Tiger to a FreeBSD 6.2 Intel server. All clients are
connected to the a 10/100/1000 switch.
* Is there anything I can tune on my server?
* Is the problem with NFS?
* Do I need to provide any other information?

I also decided to time a local filesystem write test:
