Speed Optimization for Map-Loading Application - and api app

There is a major issue with the map loading speed inside the application.
Currently, the map takes around 30 seconds to open despite having a fast internet connection. The required target is reducing the loading time to 2–3 seconds maximum without affecting any existing features or services.

I need proposed and implemented performance optimization solutions such as:

* Fast direct map opening within 1–2 seconds. In poor internet conditions, 3–5 seconds maximum, and up to 7 seconds only in extremely weak networks such as 2G. Anything beyond that is considered unacceptable.
* Reducing repeated loading requests
* Cache system or preloading
* Any suitable solutions to improve responsiveness and stability

Also, improvements are required for the mini map inside the place description:

* Improve speed and responsiveness
* Hide icons after zooming in beyond a certain level
* Remove place names and unnecessary elements
* Reduce elements that cause lag or do not add value to the user experience

Additionally:

* When pressing a category and then “View All,” the page/data should not reload completely. The transition should remain connected to the main animation flow and not feel static or rigid.
* Properly link the description inside the menu section (simple fix)
* Improve sorting by nearest or category (simple fix)

Priority:

1. Map opening speed
2. Stable icons during browsing, or after selecting a category and returning to the main category or favorites
3. Keeping all existing services/features working without any negative impact

The other file/project is considered relatively separate, and we can agree on both together or handle this task independently.

For clarification, there is a video inside the link explaining the issue and the required workflow.


There is another separate API file related to the rest of the application, and it should be considered an independent task/project.
