SOLVED Trying to find the bottleneck... LACP bandwidth does not exceed 1Gbps while my client has a 2Gb LAN?

[devnullius]

I just enabled Port Aggregation. My router has 2 dedicated LACP ports which I connected to my 2x NIC of the FreeNAS server.

Now I'm testing the network transfer speed and improvement is not that much... I now touch about 900Mbps. It should be more.

The pool I transfer to should support 8x 300MB/s/disk (about 3Gbps/disk). The network connection should be at least 2Gbps. The file(s) I'm transferring are big backup files from Windows Backup. I used link aggregation on my server too. While not the dedicated 2x LACP ports, windows happily reports a 2Gbps connection speed.

See my signature for the specs:
My htop is >100. Reporting --> CPU gives a value of about 70 (60 to 80 in the graphs). Wired RAM is 38GB. HDD usages is low.

What would you guys first impression be here?

This has been asked and answered many times on this forum. Single client connections will not benefit (speed-wise) from LACP in FreeNAS, but it can increase the server bandwidth for multiple clients.

If you want faster than gigabit begin upgrading stuff to 10 gigabit

Next year ;p 2Gbps would do for now. Router is ready; my NAS isn't.
