Slow loading large number of files on an SMB Share

The issue: loading and displaying smb shared directories with larger number of files (4,000 and up) takes minutes to load each directory using Finder. My Mac and server are hardwired (Cat6).

I have tried everything:

1. Disabled DS_Store on shares
2. Disabled signing_required
3. Enabled samba apple extensions according the
4. Disabled preview icons
5. Disabled calculating size
6. Default to list mode, sort by name.
7. Disabled all columns, just leaving name enabled of course.

The list goes on an on.

When I try to access the same smb share (using the same samba user) from a Windows 10 PC, the file lists are loaded instantly. As a matter of fact I tried with my android phone over wifi an the file lists are loaded instantly.

If I try to copy a file from the Mac to the SMB share I get 110MB/s, so speed is not an issue. So it is safe to say that the SMB Server is not at fault.

The mac seems be trying to load either file metadata and something else that delays the display of files. This is unbearable and it is affecting my work.

I would appreciate any help or update if this is a known bug with SMB on MacOS.

Thanks
