Hi. I have a custom FreeNAS build that serves me well for the last five years. All of the clients in my home network use WiFi so didn't notice any issues until I plugged my Macbook to LAN cable the other day. I noticed transfers of 30-40 MB/s when transfering large files via SMB. That should be fine for WiFi but for LAN I would expect to see values closer to 1Gb/s (so 3-4x times that). I ran quick iperf3 test and this one looked fine (I got around 900 Mb/s). I thought that maybe there's something wrong with one of the disks but dd tests look fine too (235 MB/s write and 272 MB/s read). I thought that maybe this is something related to SMB so I tried NFS -- I got only slightly better results of ~40-50 MB/s (I would still expect to see over 2x this). I'm out of ideas myself - does anyone have an idea what's going on?
My setup:
CPU: Atom C2750 (Supermico A1SAi-2750F)
RAM: 32GB
ZFS Pool: two mirrors striped (2 x 3TB and 2 x 8TB, all WD Reds) with encryption
Network: 4 x 1Gbe LACP LAGG connected to my switch (HP OfficeConnect 1820-24G); Macbook connected via USB to a single 1Gbe LAN cable.
