[Samba] super slow directory listing Samba 4.10.13

[Chad William Seys]

Hi all,
   Does anyone know of a bug relating to Samba 4.10.13 being super slow 
listing directories with lots of files for Macintosh but not Windows?
   In a directory of about 3860 files and 30 subdirectories, I get this 
result:

Accessing with Macintosh 10.15.3
  ~3 secs Samba 4.5.16+dfsg-1+deb9u2
  ~3 secs Samba 4.9.5+dfsg-5+deb10u1
  ~3 secs Samba 4.9.18 (Van Belle)
~18 secs Samba 4.10.13 (Van Belle)

Accessing with Windows 10 is nearly instant with all the tested versions 
of Samba.

I do have vfs_fruit configured.

Thanks!
Chad.
