Readynas 6 Jumbo frames optimization, SMB versions OS4 & OS6

Thanks for tips here. I have successfully improved network speed with this setup (see below). Testing with ping -f -l 4000 was important (Thanks Myles Gray). I found that the bonded ports using Adaptive Load Balancing, both ports before bonding and the bonded port set to JF=4000, fragmented the ping. However, setting the Bonded port to JF=4018 (same as the sending computer NIC) fixed the problem.
Setup:
Pro Pioneer, upgraded RAM and OS to 6.3.3 Beta 11, 8MB non-ECC PC6400 Corsair, Static IP, SMB, Switches: Netgear GS108e Jumbo Frame capable, Trendnet TEG-50 Jumbo Frame capable, Computer: ThinkPad W510 Win 8.1 x 64 Crucial C300 SSD NTFS, Intel 82577LM JF 4018,

Using NAS Tester 4000 Mb transfer,
JF Effect:
(1) No JF, No bonding...108 MB/sec
(2) JF, No bonding...119 MB/sec
(3) Adaptive Load Balancing Bonding + JF ...119 MB/sec

So, why use bonding? The speed of Shadowprotect backups has increased 2.5-3x with Bonding compared to JF only, now 70-90 MB/sec. With JF only, 50-60 MB/sec.

I am waiting for a Processor upgrade to arrive and maybe that will further increase speed on the backups.
