SUMMARY, Part 2: File sharing

Here's my original message:

We have an Ultra 450, 2 GB RAM and 2 CPUs. Attached to it we have an EMC
storage array along with an ADIC tape library. We want to backup user data
files to the E450. We have an HSM solution from UniTree that we're trying
to put together. Using samba, we've run some tests and find that we are
getting very poor performance with samba. I've run iostat, nfsstat and
rpcbind and have found Solaris looks fine. samba and/or UniTree seem to be
the problem. In one test we ran, we renamed files. UniTree/samba only gave
us one file rename a second. UniTree says that it should be around 20
renames a second. Does anybody have any real-life experiences with any
other HSM solution? Would Hummingbird's Maestro work faster than samba?

I two more replies. One from a person who works for a third party vendor
asking me if I have checked out his product, and yes, I'm already in the
process of doing that (I would mention who it is, but I'm not sure if that
would be cool or not). The other reply was from Jon Bernard
[] who said to check out the speed documents in
/usr/local/samba/docs/textdocs. These didn't help, but thanks for the

If anybody else has any other suggestions, I would appreciate a response.
