You do know they (well the 1036) can't route more than ~1Gb/s on a single tcp stream . another feature that's coming in V7 (actually mentioned in the Melbourne MUM slides under beta V7 I believe) A -----Original Message----- From: Public [mailto:public-bounces@talk.mikrotik.com.au] On Behalf Of Matt Perkins Sent: Monday, 25 January 2016 2:24 PM To: public@talk.mikrotik.com.au Subject: Re: [MT-AU Public] FW: CCR performance testing again Oh FarQ. I just did a big roll out on 1072's with LACP everywhere. The customer required 10gig's and redundancy it's not finished yet luckily but they are going to ask serious questions when i turn this off. Not happy Jan. I sure wish there was a warning box that alerted you when fast path was not being used when you use a feature. To reiterate. FarQ Matt.

Hi
Thanks that's good to know.
The list of things waiting on V7 is growing......
Not being able to LACP is rather limiting ???
I guess I could do something like
10G Switch A -> CCR1 -> CCR2 -> 10Gswitch B
Where Switch A & B are stacked .... that would remove the LACP and make a L3 link between CCR's but L2 ?.. sigh

Hi Alex, List.
Bonding (LAG/LACP) is NOT currently supported by FastPath on Mikrotik routers.
I have been in contact with Mikrotik support about this several times now. Mikrotik managed to get FastPath RX working in RouterOS 6.x, but not TX. I have not received an ETA on being able to do FastPath TX and RX.
This is almost certainly the reason for your performance issues.
Hopefully they add this in v7. We almost always put our CCR's behind MC-LAG switch clusters for redundancy, but the lack of bonding + fastpath is severely limiting performance in this configuration.
Regards,
Andrew

No
Same vlan, different ip network.
Why would it be sending redirects.
Src is 192.168.213.52 dst is 10.172.213.51. Just because they are the same vlan doesn't allow them to talk directly (normally)
Packet path is 192.168.213.52 -> 192.168.213.2 (ccr) -> 10.172.213.2 (ccr - same interface) - > 10.172.213.51
I have setup another test such that it doesn't do this. Instead in one interface and out another interface ... Again > 3G floods the CPU :(.....

In and out the same interface.. as in vlans? Or two actual subnets on the one physical network? If it's two subnets on the same network, it should be sending an ICMP redirect back for each packet that comes via the router, which would certainly be maxxing a few CPU's?

Hmmm
No
Iperf at 3G udp
All 36 CPU's are up around 96-100%
It's a hairpin route in and out the same interface .... not sure if that's the problem...

I think I have found my problem.
This is a replacement CCR1036-8G-2S+ 6.33.3
I replace the config with a config from a previous ccr.
All the mac's are not the default ones. I am presuming that's causing all the packets to hit the CPU's
My other CCR sitting next to it, same config (diff ip's) same package.
Will advise when I get a chance to reset it

Hey Alex,
It should be fine, but can you provide an example of your test config and the routers software version? Is the test single or multi-threaded, tcp or udp?

Hi
I'm testing switches again and doing a comparison to the CCR.
For some reason I can't seem to get past 1Gb/s without losses on my ccr1036.
Now this could be my VM's as VM to VM I can only get around 2-3Gb/s before iperf starts complaining ..
How are other people's experience with the CCR's I know about the 1Gb/s tcp stream limit, but I hand heard of any issues with UDP.
Infact I was pretty sure I had push it up to 9.8Gb/s.. but that was a while ago
