Hi David, Good day to you, and thank you for your e-mail.
Most of my templates are on 100 GB root disk, which I understand is too big. I plan to recreate the templates on a 10 GB disk, which should be sufficient based on an advice from another member of this mailing list on another thread. Do you think that might be the cause? I hope that deployment time will be much faster after I recreated the templates. Thank you.
