Desktop app very slow encryption and decryption

Hi all,

I was testing Cryptomator Vaults with MacFUSE on Nextcloud on Premise and it seems I encountered the same performance issues.
It occurred with Word and Excel documents but also with photos.
I did the tests with a Vault quite empty (less than 30 items).
It is not a constant issue which is disturbing.

This test was because I wanted to use it professionally but it is not possible with this trouble.
Users won’t accept to waste time like this.
It seems to be a very good product and it would be a pity having to choose another one because of this.

I would really appreciate if someone could bring information on where it could come from.

I am not a developer and cannot help this way but I can give time debugging this.

Thanks in advance
