RB850Gx2 Expected Performance

antsh · Fri Jan 02, 2015 9:00 am

Hi Everyone,

I have a quick question about the performance of the new 850Gx2. I am currently running an RB450G at 800MHz. I currently have a 130mbps/12mbps pipe, and am going to upgrade to something closer to 175/20. With the below configuration and it running at 800MHz, the CPU hits about 85-90% utilization. Since it is at around 90% at 130mbps, I am thinking that I might want to get something with a little more power for anything faster. I would really like something fanless, and the fact that the 850Gx2 would fit in the same case is a plus.

So would the 850Gx2 be faster than a 450G@800MHz? Would it be fast enough to do what I am doing now at 130mpbs but at ~180mbps?

Thank you.

Up to around 300 Mbps WAN-LAN throughput should not be a problem with an RB850Gx2. If you need more than that, look @ RB1100 or CCR1009.

Thank you for the response. Would you know if it is 300mbps just nat'd throughput or will it be able to do 300mbps with the kind of queuing I have set up?

WillMoore · Sun Jan 04, 2015 7:54 pm

300Mbps is around the maximum real world nat'd WAN-Lan throughput with a basic/efficient firewall in place and no queuing. I am not sure what effect queuing will have, but my guess would be that 175Mbps on a RB850 should not be an issue.

If you want more headroom throughput wise in a similar form factor to the RB450G/RB850Gx2 the ERLite-3 might be worth a look. If you don't mind the size and the non fan-less aspect and prefer to stay in the MKTK world... the RB1100AHx2 can be acquired for pretty low prices from some of the U.S distributors as of late.

Hopefully at some point in 2015 we will see something price/performance/form factor wise from MKTK that slots between the RB850Gx2 and RB1100AHX2.

600Mbps real world WAN-LAN nat'd throughput, 250-300Mbps single tunnel ipsec throughput and a form factor similar to CRS210-8G-2S+IN for around $200.00 U.S would probably sell pretty well.

I have actually tried the ER3L. Even though it does have hardware offloading of forwarding, queuing is all done in software. With the ER3Lite, shaping of traffic maxs out the CPU at about 95mbits. This was actually confirmed my their support. This is why I'm looking at the 850Gx2.

Mikrotik Staff,

Can you comment about when you might publish performance data for the 850Gx2 on routerboard.com? Most of your other routers have published performance charts at the bottom of the product page. I understand it should be faster than a 450G, but making a quantitative statement would be much more helpful.
