Try with thousands of files within a single folder to be sure. I had the speed limitation on LAN with USB tethering.

This Android limitation has been thorougly discussed here:

> Personally, I cannot really agree. I have one specific folder that contains two subfolders - one with 1000+ files in a single folder, and another one with 3000+ files. Syncing this folder for the very first time on Google Pixel 8 (which came with Android 14) takes 5+ hours. On the other hand, the same folder syncs in ~5 minutes on an old Galaxy Tab running Android 7.

I rather suggest for anyone to see if the new Linux Terminal app in the developer options has this limitation too despite running in a VM. It has access to the Android download folder in `/mtn/shated`.
