Yes, this delay is understandable. You are using `stored variable` which has a similar mechanism to those of `cloud variable`. Essentially those variable will verify and pull data from your device’s storage which are much slower that `app variables` If you hold the stored variable value in an app variable and compare it then you will see a huge performance in time. Doing that, however, will require a kind of management approach to keep the main function of `stored variable` which are to retain values between sessions. ---

Thanks. That stored variable is not crucial to the app’s operation. I can transfer the value to an app variable to use in that loop and then just save the value to the stored variable as needed. ---

So… interesting update: I was seeing my app take 6.8 seconds to load 25 photo+text entries from Firebase. I timed various block combinations within my “for each item j in list” loop and found that the retrieval blocks were only taking 1 second. The remaining 5.8 seconds were taken up by this little block: ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/9/9/99269826dbf17bb58f0ff17cc41f73ea55d2a671.png) I had added it because it seemed to slow down the loop a tiny bit (or so I thought!) and allow the data to be synced properly without missing anything. But removing it speeds things up dramatically and so far… the data seems to be there as expected. ---

Thunkable updates the screen when it hits a wait block, doesn’t it? So you were perhaps doing an extra 25 redraws on a complicated screen, rather than once at the end when the loop finished. ---

I think I’m going to have to give up on cloning components. I just tried using a built-in Data List Viewer layout and it was so blazingly fast that I’m just going to stick to that for now. ---

Sorry to hear that. I have a project with buttons as part of each list item - hoping it won’t be too slow. 🙂 ---
