10GBASE-T for Mikrotik

I have:

  1. NAS server, 24 x SSD in stripe of 3 x raidz2 as main pool, 8 x HDD raidz2 for surveillance video adn X550-T2
  2. Backups server 11 x HDD in raidz and 4 HDD in stripe of mirrors (zfs or course), x540-T2
  3. Workstation, Samsung 960Pro, x540-T2
    All of them connected to CRS-317 with 4 x S+RJ10, backup and NAS has cross connection, so each server connected by one wire to CRS317 and Workstation has LACP with 2 links.

I was able to get about 9Gbit (~8900-8800) through CRS317 and slightly above 9Gbit with direct patch cord between servers. For testing purposes I used iperf-3.1.3.
But here you also can see a topic that shows some issues of these SPF+ modules.

The rest clients are 1G mostly, except 4 cameras which are using own 2960 switch, that has 100Mbit connections.
