As I understand, he is building a new PostGIS on Azure for us. I will ask him. I would like to understand the matter much better for various reasons. If you are aware of technical papers or articles on the subject, it will be useful to me. I have been discussing the matter with another manager. I am also thinking about how to frame up a project as a formal project for the IT person. If you have ideas, please let me know. Basically, approaches and methods, areas to be investigated for tuning up performance. So that, I can pass the information to him. He is technically excellent, but has not got much experience in turning PostGIS for improving performance. I need to do such type of work, in order to not only solve the problem, but provide justifications to secure his job. I hope that you understand. Regards, Shao
