Win Explorer transfer to an SMB share is much faster?!

Post by *olympia76 »

Transfer speed of a large (>4GB) file to an SMB share over a GB network:
- Win explorer: ~55MB stable
- Total Commander(also use big file copy mode): vary between 28-42MB/sec and jumping up and down
- Total Commander(default copy method): ~29MB/sec stable

There is no any firewall or antivirus sw installed.

Do you have an idea why is that?

Thank you in advance!

Recommendation:

"Configuration -> Options..: Operation,Copy/Delete"
[x] Use compatibility mode for the following drives
* (all drives) or \ (network only)

This should be faster than any manual optimization, and in some cases (special NAS drives) more secure.

BTW: This is the default copy method for TC7.5:

Thank you Holger! This was fixed the issue.

I wish I had find out earlier that my slow network transfers are caused by TC. I was strugling for a year to find out the reason.

I installed XP, Vista, Windows 7 numerous times, and Linux.
It was only OK on Linux, so I was always looking for windows tweaks.
Unfortunately I was always trying to transfer by TC on Windows, until yesterday, when I was copy something via Win explorer by accident.

You can imagine, that I was shocked :)

So making CopyFileEx copy method default in 7.5 was a very good move. (I also tried to copy something on the same disk (target+source), and it was also a lot more faster with compatibility mode checked).

Thank you again for your quick and efficient help!
