Hey hope someone could point me what i could be doing wrong.I have some basic QOS rules i created for few routers i use for my customers, now first time i installed new HEX3 and on fast optical link going up to 250mbit / 150mbit im having speed issues.
I copy pasted rules i use on 10 other rotuers which work fine and i set Queue tree limits to 300mbit for testing purposes but i get only 130-140mbit downstream on speedtest, if i disable all queue tree i get full speed of 250mbit.Upload speeds are normal entire time, just download slow!
If i disable few queues my speed goes UP, if i add more of them speed drops for every mangle + queue rules.Usually i have up to 100mbit links and i never so such problems, this is first time i have this speed internet and this kind of problem.I tried everything possible to debug it from changing queue types, i monitored resources cpu never goes above 50%, there is 200mb+ RAM free, upgrading to latest routerOS, changing how packets are marked etc..
EDIT:I just now tried disabling all mangle + queue tree rules, i created single Simple queue, i set as target my lan exit port or target IP, i set limits to 500m, again, speedtest i get 140/140mbit speed, huh ?
On a different scenario but I have the same problem. Many simple queues on a CCR1009, CPU is fine (<50%) but throughput is really limited. Disabling queues makes it flow without issues.
I don’t know what to do.
Yep seams same issue as me, and i just got replay from MT, here is what they replied:
"Hello,
Check /system resources cpu, most probably you will see that one CPU core have reached 100%. As one simple queue can be operated only by one CPU core, that applies limitations. You need device with more powerful CPU cores for such queue setups
Best regards,
Janis M."
Seriously MT?Do you even read properly tickets?I Specifically wrote how CPU never goes above 50%, even funnier on my screenshot you can see CPU is at only 6% during that 150mbit download speedtest, so i dont understand where does rest of my 100mbit of bandwidth go?
And are you saying your brand new dual core HEX3 router isnt capable of doing SINGLE queue up to 250mbit ?For real?
Can you click on system – >settings —> resources
Then click on CPU and run your test again. You will see this will show each of the CPU cores and you can see if one is maxing out. You can then click Tools Profile to see the name of the process that is using all your resources. I believe that only simple queues are optimised for multi core platform and not queue trees. But this may have changed in one of the recent updates. you can also post an export of your mangle and queue trees. Another thing that can help is creating a rule in your firewall raw which turns of connection tracking for lan to lan traffic.
Okay im speechless now, i just loged into router to do another test and post screenshots for you, NOW IT SUDDENLY WORKS!
I have changed ZERO things, nobody even logged into router for few days, last thing i did is update to 6.40rc2 when was out and tested once more in hope it somehow got fixed(it didint).
Now im getting full 200+mbit speeds and cpu doesnt go over 50% cpu regardless of Simple queues or Queue tree that i have previously set when it didint work.
Now im not sure if its random bug, or was it fixed and i missed it somehow, will monitor if this problem will appear again..
Keep us posted. But it would be good to see what the cpu usage is per core and also see the profile of which resource is using the cpu.
I am yet to get my CPU usage above 14%. The dude uses 100% of one core which pushes my total usage up to 14% acround 9 cores. Queues and queue tree have not gone above 1 % on any core as yet.
@ivicask: what others are saying is that in multi-cpu boards (like your hEX or my CCR) some processes that don’t use multi-threading can consume a single core to 100% but what you see in total (that one you see in winbox) is a fraction of percent. Given that you have a dual-cpu system, if one goes to 100% you should see a ~50% total cpu usage.
In my case I checked this and none of the cpus goes up to 100%, at worst I reach 80%, still I suffer of the same wrong behaviour.
I understand this, but my total CPU usage when it was broken was 6%, and individual cores(2+2 multithread) where never above like 50%, i understand everything, sorry if im bad at explaining problem, i was about to post the screenshots form profiles, but as i wrote above now suddenly all works..
Side question, is mangle + Queue tree supposed to use multi cores or not?From what i see when running test now when it all works properly it does use all cores or im seeing wrong?
Well i have simple mangle rules, and as long everything works and CPU isnt crossing even 50% total i dont want to touch anything..
But as i said original problem was with ALL firewall and ALL mangle rules disabled, just single Simple queue and bandwidth was cut in half, still cant explain it why it happened, but it did, i submitted supout logs to support during when this problem happened but i guess it doesnt help them much..
Here we go again, problem is back, nothing was touched in configuration, i tried again disabling all firewall, mangle, Queue tree rules.
I set single simple queue rule, limit it to 500/500mbit, i get top 170mbit on speedest
I disable simple rule i get 250mbit again.
Comparing to my previos screenshot above when it worked i see there is something different with CPU, when it worked properly it used CPU0 to full + CPU3 and CPU0.
Now it tops CPU3, and other CPUs are barely used.
Im 100% Sure this is some kind of bug in this Device multicore management / task distribution.
Cant we do some proper debugging?Im willing to give Team Viewer acces to my server if some Mikrotik technician wants to check whats going on.
I’m using Queue tree, this is just example so someone doesn’t tell me how mangle or Queue tree rules are bad ,or how i should change that or that, thats why i disabled all rules for test.
Performance issue happens with both Queue tree or Simple queue.
And does it really matter?Its brand new powerful router, i should be able to do simple queue limits if i want, and it does work as shown im above SS, but seams there is some kind of bug which im trying to debug/prove now..
are you not under some sort of attack. I find it weird your router is hitting 28% on firewall as well as queues. confirm how many clients you have running off this. can you do export on your firewall.
But even if disable all this rules it makes no difference on speed or firewall load, i completely disable all firewall related rules, makes no change..
EDIT:I mean if i was under attack wouldn’t i see higher firewall load during no traffic?It only goes up during speedtest..
