transferrate drop with tcmd 5.51 when copying to Samba share

[Andrew]

Hi,
I had been using Wincmd 5.0 shareware some time ago.
As the name changed and the version got up to 5.51 I dl'ed the latest version.
I have a server running Linux with Samba 2.2.8a and my Windows comp that connects to a Samba share as drive D:. When copying a file from the local drive to drive D: wincmd 5.0 copies it faster than tcmd 5.51.

-wincmd 5.0 needs 51 seconds to copy a 375 MB file to the Samba share.
-tcmd 5.51 needs 71 seconds to copy the exact same file to the share.

That makes:
7.3 MB/s with wincmd 5.0
and
5.2MB/s with tcmd 5.51.
Using the Windows Explorer it also takes 51 seconds to copy the file.

Any ideas of what could be the problem?

André.

That's strange - the two use the same copy functions! Do you use any special copy options, e.g. CopyBlockSize= etc.?

I'm not usinga ny special options to copy the files.
But I did some more testing.
I turned on LogLevel 3 for Samba and there is one difference when copying files between 5.0 and 5.51.

When I copy files using 5.51 I have lines like this comming up in the logfile:
[2003/07/07 18:53:23, 3] smbd/reply.c:reply_write_and_X(3010)
writeX fnum=11384 num=1 wrote=1

When I copy files using 5.0 it looks a little bit different:
[2003/07/07 18:54:00, 3] smbd/reply.c:reply_write_and_X(3010)
writeX fnum=11386 num=65536 wrote=65536

This is the only thing I noticed as a differnce between both versions.

I did another test in copying files. I used a 1GB file (1073741824 bytes) and copied it from a local drive to the Samba share on drive D:
I copied the file three times with each program just to get an average overlook.
Those are the result:

--|-5.51---|-5.0---|-Explorer
----------------------------------
1 |3.17 s |2.28 s |2.47 s
2 |3.19 s |2.25 s |2.35 s
