I found out what "net usershare info" does (it prints information about a
specific samba share), but I think the issue we are facing is actually a
problem with samba as Dolphin should not explicitly call these functions. I
guess we can close this bug & maybe file a report against the samba
implementation.

What do they do? Are they necessary?

I found the net processes are actually calling 'net usershare info'
I inadvertently had usershares enabled in /etc/samba/smb.conf. 
After removing that the problem was gone.

I don't know if this still is a bug. Somebody else has to decide if those net
calls are intended or unavoidable. After all they are slowing down the process
considerably.

No, I didn't see those either. Your suspect might easily be true, as I do not
have any samba mounts (even though I don't understand how that might affect
file creation).

ext4 - probably not.
After your report I suspect it has to with the samba share mounts i have in my
fstab.
Did you see those net processes in ksysguard?

Hmm, I cannot reproduce this behavior on KDE Neon 5.12.2 with Dolphin 5.12.2.
When following your steps, I get this output:

Hit enter when files show up

real0m1.237s
user0m0.000s
sys 0m0.000s

which seems perfectly normal to me. Could this issue be related to the
filesystem type?
