Performance Query

Fri Jun 02, 2017 5:47 pm

I have recently purchased a CRS212-1G-10S-1S+ and a CCR1072-1G-8S+. I linked the two devices together using a 3m DAP cable and two of the SFP+ ports.

As per the image below, when doing a bandwidth speed test between the two directly connected devices results in what I would deem as sow performance.

Could someone please advise if there is any Fibre related settings that I an overlooking to increase the throughput,?

What happens when you change the protocol to UDP?

You should bandwidth test through the device, not on it. Generating the bandwidth is limited to a single core, so it will not reach maximum performance.

Thanks for the feedback so far. I will rerun a few tests using UDP and through the device and post the results back here.

Using 2x CRS212-1G-10S-1S+ connected via the SFP+ ports (10gb) to ports 1 and 2 on the CCR1072-1G-8S+ and performing a bandwidth test through the device gives roughly the same performance as per the image below.

Changing the Bandwidth parameters to use UDP instead gives the following results.

Considering that all these devices are linked using 10gb equipment, what type of performance should I be expecting?

You are probably maxing out the processor on the devices you are testing from rather than the devices being tested. I'm fairly certain that you shouldn't be running the bandwidth test on the CRS devices. You are very likely maxing the CPU on the ones running the test. You need something with more processing power. I haven't had a chance to play with the CCR1072s, but one of those on each end, or some decent PCs or servers running the btest software on the Mikrotik Software page I would think should give you better results.

@gerakon

Thank you for your response and it seems you are right.

I plugged a machine directly into the "CRS212-1G-10S-1S+" and tested through it to the "CCR1072-1G-8S+". The performance increased considerably however it does unfortunately seem like the "CRS212-1G-10S-1S+" just dont have enough CPU to cope with the high data throughput as it quickly hit 100% CPU. This really is a shame because I dont believe Mikrotik over any other products that allows for 10 SFP's (or more) and a 10gbit uplink?

As for the CCR1072-1G-8S+, I threw everything I had at it and I did not manage to get its CPU to spike above 4%.

Thanks for your help.

It's a switch. If you're sending stuff via the CPU (which you obviously are as it's hitting 100%), then you are doing it wrong.
Post your config. using /export if you want somebody's opinion on what.

Yep, post your config. You should have one port as master and likely the rest slaved to it. You can do VLANs without bridging, but at 10 Gb it doesn't have the CPU for bridging. If you are bridging, that takes place in CPU and will cripple it. I have a CRS125 and it works great with VLANs. If i were to setup a bridge with 20-100Mb it would probably puke.
