@roman_r_m @dpoulton
Thank you for your responses. I especially appreciate dpoulton for taking the time and providing a detailed answer. Dpoulton if you look into the topic, you will also see that my only expectation was to receive a detailed response like yours. While I respect and appreciate the contributions of other respondents, I must emphasize that your response and approach are ideal.
As you can appreciate, aside from provocative aspects, through this topic and your post, people will develop a strong belief that the "days-long" synchronization process is generally due to factors outside of Joplin. I believe this is an important step towards better understanding the synchronization process. If I had seen such a response before, I would have been more careful in framing my topic to avoid misunderstandings. In fact, my suggestion to you is to issue a general warning considering people who are considering transitioning from applications like Evernote or Notion, which have their own servers, to Joplin.
However, let's not misunderstand here; there are note-taking applications such as Obsidian, Simplenote, etc... that do not allow for alternatives other than their own servers and charge monthly or yearly fees. I am not comparing Joplin to them, and I consider Joplin to be superior because it grants users such freedom.
Regarding your question about code, I am not knowledgeable about coding. In my response to Roman above, I mentioned that I don't know if a possible bandwidth limitation, being server-related, would be present in the application code. Therefore, I am not asking you to show me something you don't have. I am asking as developers if you are throttling bandwidth. If you, as far as I know as a developer, say that such throttling is not happening, then of course, I will believe you. However, as you can appreciate, companies, for example VPN companies, can market what they do as not doing certain things for consumers, such as keeping user logs or even selling them to advertising companies. Therefore, Joplin is also a company and deserves to be questioned.
English is not my native language. But as far as I know, the word "manipulation" does not imply insult. I have never had any intention of insulting in my questions. On the contrary, I opened a topic for explanations from you and other developers. But even if I was mistaken, you can appreciate that the way to correct a mistake is not by the other party making a mistake as well. So my question was never a hypothesis. I just asked a question. That's why I used the term "necessity" in my topic title. Nevertheless, I apologize if I was misunderstood or offended anyone, including you and @laurent . As I said, I opened this topic not to blame but to get information.
Besides, as a user who doesn't know code, it would be quite audacious even for me to propose a hypothesis to those who do know it!
One final suggestion, please consider creating a guide for Nextcloud and WebDAV for Joplin by yourself or knowledgeable people on the topic. This way, we can get rid of third-party software like Onedrive and Dropbox and improve our own solution. This would also strengthen the argument that Joplin Cloud is optional.
