Hi Evanthika, Having a mount and not having a mount (at least based on recent performance tests) did not show significant differences in times. However, if the mounted DB is either remote (or local and heavily loaded) a delay of a certain factor is expected. I don't think that it should be considered to be show-stopper.
Thanks, Senaka.
