Wait wait wait wait wait.. Mikrotik 10Gbe is a scam...??

I have a CRS326-24G-2S+RM, with 2x SFP+, namely, 10Gbp ports. That’s the reason I bought this guy.

CRS326-24G-2S+RM	98DX3236 all port test
Mode	Configuration	                1518 byte	512 byte	64 byte
                                       kpps	Mbps	kpps	Mbps	kpps	Mbps
Bridging	none (fast path)       104,3	1266.6	273,5	1120.3	449	229.9
Bridging	25 bridge filter rules	104	1263.0	104,6	428.4	104,5	53.5
Routing	none (fast path)	       104,3	1266.6	273,9	1121.9	343,5	175.9
Routing	25 simple queues	       104,3	1266.6	136,9	560.7	137,4	70.3
Routing	25 ip filter rules	         64,8	786.9	65,9	269.9	65,8	33.7

But the max bridging throughput according to this test is 1.2Gbps.. and even if I take only switching it’s only 4Gbps:

Switching Non blocking Layer 2 throughput 3,576.1 43,427.8 10,338.3 42,345.9 65,476.2 33,523.8

So am I getting this wrong? Or have I been duped?

Ethernet test results I think is routing not switching.
Switching result with 1500 bytes is as you write 43,427.8 Mbit which is around 40 Gbit. So there should be no issue as long as it is correctly configured for hardware offload.

ok but.. 10Gbe then only usable on L2 and only with HW offload turned on.. which introduces other restrictions, or not?
How do I make sure that is enabled then?

So you have bought a switch and not a router, but a switch that can act as a router (Cloud Router Switch, stupid name I know)

So you should only use these for switching and perhaps light routing tasks so primarily L2.
Read more here on how to make sure you use correct config in ROS.

I have 2 of these switches and use them only as a switch running ROS. Then I have 4011 doing routing connected via 10 Gbit SFP+ port.

Well, I guess I can survive that way but it seems odd to then offload routing to a consumer wifi AP (running OpenWRT). Makes me re-think my plan to throw out my PowerConnect 6000 that is super noisy and uses a ton of power (5x the CRS). At least the CRS is much prettier…

I’ve considered the RB4011 as well. Currently debating whether a thin-mini ITX i5 in a tiny box for about the same price and running pfsense would be a better option than the RB4011. I guess it’s not too likely that I’d be sitting on a 2Gbps internet connection anytime soon.. but then the SFP+ would be wasted since I need 2 SFP+ for my local devices and that removes the ability to uplink to the RB over SFP+.

To be fair I don’t have a lot of heavy routing to do.. the only high data load is between the two devices that both have SFP+ and I can place them on the same L2. But then it was really a waste getting the CRS since the equivalent CSS has the same L2 performance. :confused:
