Loading assets is slow when assets are iCloud based

in both Legacy (3.x) and Modern (4.X), on iPad Pro M1, code 3.16 (but problem already there since 3.14), “require()” loading assets takes more and more time when assets are located on iCloud (even if they are in cache on my device)

File1: test_main

require(asset.icloud.test_lib) – alternatively require(asset.documents.test_lib)

File2 : test_lib

whatever you want …

Open File1, execute (CMD R), stop, exec, stop, exec, stop … takes more and more time to load and execute when the files are located on iCloud. With significant libraries, first exec could be straightforward at first sight, then leads to minutes (!) to show the left hand side panel, then again minutes of wait to execute.

Am I the only one to encounter this ?
