[Samba] Slow transfers when using a linux-based client vs Windows client

[Adam Baxter]

Hey,
I've got a performance issue when transferring files from a Samba
4.1.6-Debian server. When using a Debian client, I get around 4.5 megabytes
per second, but when using a Windows (8) client I get around 21 megabytes
per second!

Any idea what would be causing this massive discrepancy?

Compressed pcapng files are at
https://mega.co.nz/#F!W5IygDzS!2bIAxA3tOpEvvgQf1HForw
- they'll unpack to around 500 megabytes each.

I'm fairly sure I filtered these well but please let me know if I've
managed to post my credentials in these files... although the shares I was
testing with were guest/anonymous allowed.

Thanks,
Adam
