I have been trying to push the sync speed to the limit, as the server was offline for a while and I will release it for general use only after it's sync'ed. So, nobody is using and I can use full speed.</div><div style="font-family:Calibri,sans-serif">
<br></div><div style="font-family:Calibri,sans-serif">I have two servers, each one connected to a NAS unit through a CAT6 cable, no switches in between. It's 1000 Mpbs full duplex, as the ethtool says.</div><div style="font-family:Calibri,sans-serif">
