Hitting the limits of the Ubiquiti EdgeRouter
-
I have one client site that I have had to disable QoS policies because it constrains their max bandwidth causing slow offsite backups.
Does anyone know enough about VyOS/Vyatta to have any suggestions for options while retaining the hardware?
The fault here is not something I blame directly on Ubiquiti, because I do realize that it is simply not possible to ASIC offload traffic inspection like this. I do not know of ANY device can do this. It is simply not how the technology works.
I know that I could jump to a full VyOS system on some desktop hardware or a even VM to gain enough CPU power to handle this. I am trying to avoid that if possible.
Basically, if I use the
traffic-controlsettings with FQCODEL, I never get more than ~35mbps. If I use thetraffic-policywith % limits and DSCP matching, I never get more than ~60mbps.This has never been a problem before now because line speeds have been less than 50mbps. But now I have clients with 100/100 fiber lines and we want to get the most out of the upstream as we can with offsite backups.

I found some sites that might help solve this issue you're having.

I'd like to know this as well. Depending on what I hear back on a project, I may have to recommend something other than Ubiquiti.

@JaredBusch, The ERX, ER8, and Infinity all have faster processors and more cores than the ERL. I know that the ERX has other failings, but it handles QoS and OpenVPN much better than the ERL does.
The ERL could not handle fqcodel on my 150/150 but the ERX could. It may be worth the $49 to test it.

http://xmodulo.com/how-to-set-up-qos-bandwidth-rate-limit-vyatta-router.htmlI know how to perform QoS in more than one way on EdgeOS. The problem is that you cannot offload QoS traffic, so that means the processor has to handle it.
With QoS processes running, the CPU pegs and the the bandwidth is as noted above. I get that, and I expect that.

The
fqcodeloption is worse than just DSCP checking. I could only get 35mbps out of it on an ER-PoE or an ERL, when the DSCP style gets me 65mbps. -
@JaredBusch So what is the solution to hitting the limits?

Change how you use it or but the next size up unit.

I just saw the price of the Infinity lol I realized I need to go down a level
I'm hitting the same issue. I think we have maxed out our Edge Router (it get's insanely hot and utilization is often spiking to 70-90% with the QoS enabled.I also so my 300 Mbps download speed drop to 100-160 Mbps (if I was lucky) and my 20 Mbps upload speed dropped to around 10-12 Mbps with the QoS enabled. I don't think it can handle the number of endpoints, QoS, and packet filtering we have on it. But at my other site, with same router but less people, endpoints etc they are just trucking along just fine. Of course there on a 100-150 Mbps download and 10-15 Mbps upload. But I think when everyone is on with every device, it's handling it fine.

ER-X or another model? They're all limited when doing QoS, so not really a surprise, but the other models all have a little beter cpu.

Which one is considered the next size up?

The ER Pro is the best model.

Well shy of the brand new infinity

The ER-Pro or Infinity do not suffer from the same constraints as the ERL?
How is VPN performance on the ER-Pro & Infinity?

Of course they have the same constraints. But the processors are different, so the maximums will be different.

I discussed nothing about VPN performance.

@jaredbusch VPN performance is better than my SonicWall. It's obviously better than my old linksys too lol. But with a 300 (up to 400) Mbps and 20 (up to 30) Mbps internet, I want as much bandwidth as I can get.

If you want to ask about VPN constraints, there are basically none. You can get near line performance for anything short of 500mbps as long as you have it properly offloaded.

@jaredbusch My apologies, I meant QoS!

"Better than my SonicWall" is the networking world's equivalent of "it out performed my Pinto".

Well then, yes, better QoS performance because better processors.
