We did exactly this for our DB servers (and left them there) and tested
it with 1 fileserver for a bit.
Your best bet is to quantify "current slow" with data, then stand up a
few test VMs (2core, 4core, various fileserver params) and gather their
performance data under the same tests.
Unfortunately, our fileservers are still left on the old Suns while we
figure out whether or not we're willing to stoop to XFS on RHEL (support
contract, known choice of OS) or add complexity to our world by using
OmniOS or FreeBSD to retain ZFS.
