High CPU and latency spike on RB750Gr3 during downloads
Hi all, Am running RB750Gr3 firmware 7.13.5 with the out of box factory configuration for internet router. I have disabled RSTP on the bridge. On NBN FTTP 100/40 plan with NTD connected to eth1 on the RB750Gr3. Rest of my internal LAN is connected to eth2. When I max out a download or run a speed test at 100Mbps I find the CPU on the HEX is getting up to 30-35%, and on upload around 20-25%. At the same time I see in all my pings beyond my first hop ISP gateway that I get a big spike in latency which feels like the Mikrotik is struggling to process the traffic inbound. I thought the RB750Gr3 was good for up to Gigabit speeds, but even then I'm only asking for 100Mbps - is there anything I need to tweak further in the configuration to fix this or should I be looking at a newer router like the L009 series, will that provide smoother throughput ? Thanks, Chris
Hi Chris, Are you directly connected to the hEX or is it through the supplied NBN switch? Those switches are only Fast Ethernet.

Hi Alen, Yep the hEX is directly connected from Port 1 to the NBN Alcatel NTD Port 1, I get the Gigabit link light up on the NTD and the hEX indicates ether1 autoneg'd at 1000Mbps full duplex so no problems with speed between NTD and hEX.

Hi Chris, There are a few areas to look, particularly your firewall config, also, profile your cpu usage so you can get a picture of what processes are consuming the CPU then we can provide further advice from there. Are you maxing out a core with firewall or networking processes? The other place to look is queuing, fq-codel can be your best friend in times like these.

Hi Dirk, When I profile the total CPU usage it moves pretty fast, but it roughly looks like this during a heavy download:- Networking 15 Unclassified 12 Firewall 5 Not sure what Unclassified is, my understanding was the default "Fasttrack-connection" entry in the FW should hardware offload the processing of those packets,. The special dummy rule at the top of the tree only shows around 3-4Mbps of traffic when the speedtest shows 102-103Mbps. This is the firewall entries I have, the only thing I've added is a DST-NAT entry to RDP in.

Thanks Mike, I have implemented fq-codel and it's made a huge difference, took a bit of trial and error and working out that the upload/download limits had to be reversed from the point of view of the WAN interface. That said, I am finding a bit of conflicting info on how to best tune it, for instance on the Ubiquiti forums this post below suggests disabling ECN for uploading, but still keeping enabled for downloads. I'm also a bit confused regarding the fq-codel queue configuration, some people suggesting the Quantum should be 300 for up to 100Mbps connections, and 1514 more for 10Gbit connections? Anyone have any suggestions on what they use for a NBN 100/40 connection? I know NBN over-provision the bandwidth slightly and I've had up to 104Mbps on speed tests before, so I've set the upload (really download) maximum to 100M, and for the download (really upload) only seems to kick in queuing if I set it to around 32M, as the best I've ever really gotten in speed tests is around 36Mbps up. https://community.ui.com/questions/Best-Practices-for-Smart-Que-tuning-FQ-Co...

I have been using CAKE lately. For a 100Mbit/100Mbit fibre link this is the setting that gets an A+ on https://www.waveform.com/tools/bufferbloat with jitter under 5ms each way. I had to do repeated tests until I arrived at using RTT=150ms as the magic number. Another site with a 200/200 link the RTT is 175. I have never used queue trees in my life, simple queues have always sufficed.

As it's the only item in this queue I think it's fine to set the limit in CAKE itself. If I was doing parent/child hierarchies it'd be different. I am using CAKE on 4011 and 5009 routers that have plenty of beefcake CPUwise. The ol' hEX might have an issue. Don't forget to keep in mind the different ethernet bus arrangements if you have switching enabled or disabled. https://mikrotik.com/product/RB750Gr3#fndtn-downloads
Hi I was not able to get your example to work, all local traffic would stop, but using the example in the link I have in my first email I was able to get A+ https://www.waveform.com/tools/bufferbloat?test-id=dbde0dcc-3ba1-4d07-8732-9... Connecting via WIFI and doing that test gave me a D, so I'll need to do some work on the WIFI here at work. Mike On 4/3/2024 6:41 am, Jason Hecker via Public wrote:
