I am having trouble reaching the full 10 Gigabit of transfer throughput.
The drives on the server would be easily able to do that.
About the Server:
OS: FreeNAS 11.3
Network: Intel x550-T2 card
Storage: 4x NVMe (PCIe 3.0) SSDs in RaidZ1
Pool write test:
Results in 1.9702 Gbytes per second!
Pool read test:
Results in 6.924 Gbytes per second!
That should proof that the server is more than capable of saturating a 10 Gbit connection.
My networking equipment:
The FreeNAS and my computer both have official Intel x550-T2 Ethernet cards and are directly connected via a Cat6a cable.
I enabled Jumbo Packets of 9014 Bytes both systems.
On my computer I disabled "Interrupt Moderation" which resulted in a big performance boost.
I tried the config from the 45 drives article:
www.45drives.com
On my system I set the Receive Buffers to 4096 and Transmit Buffers to 16384
On FreeNAS
These tunables on the FreeNAS made no difference.
Current performance:
SMB ( CIFS )
iSCSI is similar.
FTP ( plain, unencrypted )
Any help on how to configure FreeNAS to reach 10 gigabit is appreciated!

How to Tune a NAS for Direct-from-Server Editing of 5K Video
