Only 1Gbit over SFP+

RouterOS General

Hello

i have an CCR1009-8G-1S-1S+ and i connected it to a 10G Switch with SFP+.

The Problem is that i get only 1Gbit, but in the cli it says i have 10G

                      name: sfp-sfpplus1
                    status: link-ok
          auto-negotiation: done
                      rate: 10Gbps
               full-duplex: yes
           tx-flow-control: no
           rx-flow-control: no
               advertising: 
  link-partner-advertising: 
        sfp-module-present: yes
               sfp-rx-lose: no
              sfp-tx-fault: no
        sfp-connector-type: optical-pigtail
    sfp-link-length-copper: 3m
           sfp-vendor-name: Mikrotik
    sfp-vendor-part-number: S+DA0003
       sfp-vendor-revision: A0
         sfp-vendor-serial: MT31126HXXXX
    sfp-manufacturing-date: 13-12-15

The other Switch says also that i have 10G

But when im Routing over the Interface i get only about 1Gbit. I also disabled all Firewall Rules but there is the same result. The CPU is only about 10 percent. I don’t know what is wrong. Could someone help me please?

This is a normal behavior if you have a single data stream, because one stream is running over one core and the max speed is around 1 gig.
If you have multiple streams, you get more speed out of it because it is distributed over several cores.

I was able to get 9Gbps when running a test over SFP+ using a loopback between two ports.
