Try disable the compression, and see if it improves.
Personally, I have seen Windows machine with big share size, more than 1GB
is transferring very slow. This could be due to samba have to read all the
files, generate the tarmode file, transfer the file over to the server,
extract the file, then comparing which file that should be saved.
Try to transfer a 1GB file from your Windows machine to your Linux machine
to see how long does it takes to finish.
For my solution, I changed all Windows machine with big share size to use
rsyncd. I setup rsyncd on my BackupPC, then install rsync client on the
Windows machine.
After configuring rsync client, the first backup will be slow, but the
subsequent backup will be fast because rsync algorithm check for changed
file, and only transfer that file.
You mile might vary.

Want excitement?
Manually upgrade your production database.
When you want reliability, choose Perforce
Perforce version control. Predictably reliable.
