Do you have a dedicated SLOG in your system? If not my guess is this will be slowing you down.
Strict sync means that samba obeys requests from client to flush. It’s the default for a reason.

Ah ok. I presumed it would force a client writing asynchronously to essentially sync all its writes. My bad.
It’s just a home NAS, a lot of ram is not used, so I didn’t use dedicated SLOG.
RAM is relevant to (lack of need for) L2ARC, not so much for SLOG.
Yeah only needed to enhance sync write performance.
Just commented out all MacOS connected settings and add the following line, the end is speed increased from 60MB/s to 70MB/s even 80MB/s sometimes.
aio max threads = 1000 # default is 100
I am confused now, do these fruit settings means nothing for macOS Sonoma 14.5?
OK I think my problem has been resolved. I can get about 100MB/s speed on MacOS client connected to wifi router which is connected to 2.5Gbps NIC NAS.
Also the problem of long time (2 minutes or more) to preview big directory of pictures (50k) MacOS Finder is gone too. Need to put some settings on both the server and the client. Hereby is the full settings of Samba server:
cat /usr/local/etc/smb4.conf

unix charset = UTF-8
workgroup = WORKGROUP
realm = yo.home

interfaces = 192.168.31.20/24 re0 127.0.0.1
bind interfaces only = yes
hosts allow = 192.168.31.0/24

Thanks all for your help, it’s a so nice community though I use FreeBSD 14.3 instead of TrueNAS. Thanks again.
Unless you’ve removed our vfs objects configuration this parameter has no impact at all on share (we don’t use the builtin in samba aio). If you have removed our VFS objects I’d maybe carefully test before storing important data on the share.
I am removing the resolution flag because the referenced post contains unsupported configuration changes to the SMB server that may adversely affect server stability and data integrity.
You can do whatever you want with your server, but I do not think the samba changes are appropriate to present to other users as a solution to performance problems.
