Importing 3 GB of data into cryptomator vault on Google Drive is very slow

[pinpontitit]

Describe the bug
I tried using Cyberduck to access my Cryptomator vault hosted on Google Drive. I connected it, it works I can access my files.

However I tried to import 3 gb of files inside and it was very long, I mean many hours and I had to stop it manually.

My files are a lot of very small files, inside a lot of folders.

While it was uploading, the sentence "Folder 'Name-of-folder' is being uploaded" was appearing, and the name of folders was changing always, as if it was parsing all the folders name first, before uploading the files, and it kepts showing this sentence and parsing forever.

If I upload thoses same files and folders unencrypted into Google Drive it is very fast.

Why is it slow ? Is it Cyberduck, Cryptomator, or Google Drive when using encrypted vault ?

Is there some way to solve this or I should quit using Cryptomator with Cyberduck ?

Thanks
