Very slow to show all the files in a folder on an SMB share

[dxglaw]

I need frequently browse folders on an SMB share. Most of the folders contains about hundreds of files.
1. Using Totalcmd, it takes about 10 seconds to show all files in the folder.
2. Using MS explorer, it takes almost no time to show.
3. Using double commander, it takes almost no time to show.

I further use an app FileActivityWatch.exe to monitor the file access of the three file explorers.
1. Using Totalcmd, there are read operations (first 5120 bytes) for all files in the folder.
2. Using MS explorer, there is no file read operation.
3. Using double commander, there is no file read operation.

The following shows some of the read operations. I have tried almost all configurations related to this issue in this forum. But none works.
Could anyone has any clue?

Sorry, no idea, I call the usual FindFirstFile/FindNextFile/FindClose function as for local directories.

Please check your settings for Display -> Icons -> "EXE/LNK not on net"

The fastest settings are to choose 'Only Standard Icons' or 'No Icons', prioritizing the SMB (etc.) speed over beauty.

Btw:
The inifile settings 'noreread' and 'noreread2' are also very useful, when you start Total Commander,
and the remote computer, you were working with the last time, is offline.
Read all about it in the excellent help file.
Those features has saved me from a lot of TC waiting time over the years.

Here are my ridiculous ridig settings :
noreread=ABKMNQVP\/:
NoReread2=ABKMNQVP\/:
