A couple things I can think of: * Do you have any stale NFS mounts on your TSM server? Even if the FILE volumes are not on NFS, I've seen slow access on any file if there's a hung mount. * Do you use a central directory server (NIS, LDAP, etc.) for this system? If directory lookups are slow, that could slow down file access as well.
