Hello, after trying several things to create an uber menu I managed to have a result but slow. A data viewer list for the menu linked to an Airtable. Then another data viewer list linked to a local table that is filled with information from firebase. When you click on a menu, I will look for the …

There are some known reasons that data retrieval or storage may take a long time, especially with Firebase. If you post a link to your project or screenshots of your blocks, we can provide some suggestions for speeding things up.

I could provide a link to the project but it would take a lot of time to understand because there are 2000 blocks on the page, namely I retrieve from firebase the raw JSON to speed up the thing.

[image] kushweez: there are 2000 blocks on the page, namely I retrieve from firebase the raw JSON to speed up the thing. Can you show the data retrieval part and the data selection/filtering part?

Yes, this. As I said, there are known, reproducible issues that will slow down what you’re doing. Things like using stored variables instead of app variables or the difference between using Realtime DB blocks vs. cloud variable blocks when referencing Firebase nodes.

Hi, Thank you all for your answers Here is how I get the firebase data. The menu variable stores the raw JSON of all the menus [3] Then in the variable data.fire I store only the menu I want using the variable selection.edit which contains the name of the menu I want [1] I then do the filter…

Wow… This really really takes resources and a lot of time. You know if you load your database in a chargeable cloud, usually by hits, this routine will cost you a lot. How many times this function is supposed to be called within a normal use of the app?

The JSON block with all the menus is retrieved only if one of the menus is updated by the admin, then the version of the menu changes and it will be loaded when opening the application. The json is stored as a local variable as long as the version doesn’t change, I could optimize instead of reloadi…

One thing to note. Reading from a database is obtaining data from a source external to the app which makes it slower than the variables within the app. However, a stored variable is also an external source and is as slow as reading from the tables. Secondly, you are using too many variables and a l…

Yes the external data are the menu that can change. And if I call stored variable it is for reasons of moves and avoid unnecessary calls to a database. Alas the loop is to restructure the JSON data because at the base I have a raw json code and to filter it and place it in the right place. I’ve a…

Questions about Thunkable

My experience is that as you exceed 500 block on a screen performance really deteriorates. Loops are also very, very slow. Consider building a server side process for you menu so thunkable can simply display pre-organized/formatted data.
