trying to test 10G SFP+ optics between two Mikrotik 1036

Hi,

I work at an ISP and was trying to throughput test some Cisco 6509e compatible 10G blades using Mikrotik CCR1036s on either end (each blade is in 20G mode). Each 1036 has a smf BiDi fiber optic connected to its SFP+ port 2 and directly connected to the 6509e Xenpak / X2 10G blade port with a Xenpak / X2 SFP+ converter. Pictures of optics/converters are attached below. I was able to successfully run a Btest between the two 1036’s, passing traffic through the Cisco xenpak / x2 10G blade ports. The issue is it was only able to hit 1.3Gbps RX throughput on 10G optics, during a both way UDP Bandwidth test (TX speed was low - 1.3Mbps or less). TCP both ways only hit about 250Mbps TX/RX.

I was told by an experienced Mikrotik user that it should be able to hit 7-8 Gbps with that UDP test. Is there something Im doing wrong here? Are there hardware/software limitations on the 1036’s I should be aware of? How can I push the higher throughput up to 7-10 Gbps which I thought the CCR1036 could handle across its SFP+ ports? I would like to fully test 10G through the Cisco blades.

Thank you for your help.
