Slow transfers speeds over network (SOLVED)

Hi All,

I'm having issues with only getting 10 MB transfers speeds over the network from my unraid box. This is when using either SMB or scp. 

However, when I connect a USB external storage, I'm getting 100M+ transfer speeds. I've so far not been able to identify the issue, but I'm getting it on several different NIC's while a docker containers is able to download off the internet at my full internet bandwidth (when I'm not throttling it) at 20MB so I don't think it's a hardware issue at any point, but a network stack issue.

The server is on a bonded 4 port gigabit nic into a gigabite managed switch which all appears to be working fine, so accept when then disks are over worked, I should expect to see around 100MB transfer speeds.

Can any one help me diagnose and resolve please, it's no fun having to run up and down with an external HDD to do large file transfers. Especially as it should be twice as fast over the network over the manual fetch and carry.

Attached are my unraid diagnostics.

First test is the standard Gigabit connection, second is bonded (still playiong around with the bonded connection, but show I should at least get the same speeds from this client).
