hAP ac^2 performance drop

Fri Jan 31, 2020 11:09 am

Very, very bad finding about performance of hAP ac2 for all ROS version after 6.43.16. Triple checked - for clear routing in all new versions the load is distributed over only 2 cores, which results in half of the performance in comparison with 6.43.16!!!

Test1 - ROS 6.43.16 clear routing of 700Mbps between two interfaces - RESULT 0% loss

[admin@hAPac^2] > system resource cpu print interval=1
# CPU LOAD IRQ DISK
0 cpu0 64% 57% 0%
1 cpu1 73% 73% 0%
2 cpu2 90% 84% 0%
3 cpu3 93% 86% 0%

What kind of test are you doing? Have you checked, filters, fast track, bridge, etc..?
That does not look good, looks like a case to write to support.

It is just routing. Two routes in the routing table. That is not the point. The point is that the configuration is the same in both cases!

No answer from Mikrotik? The new hAP ac2's already can't be downgraded! Should we stop using that model?

If you expect answer from Mikrotik, then you should contact them via support@mikrotik.com ... this is merely user forum with occasional visit of some MT employee...

Already more than 50 pcs installed with last stable version 6.46.2 and all of them works good! Tested all of them and all CPU works!

Same with 6.46.2. Tested with two different hAPac^2s.
Do you use connection-tracking features or features that bypass it?

I noticed that routing for cAP ac only uses 1 core on RouterOS 7.4. IPv6 traffic is also only received on a single hardware queue, but that doesn't matter if everything is on a single core. I was wondering if other IPQ-401x devices like hAP ac² was now also limited to 1 core.

IRQ info for cAP ac:
> /system/resource/irq/print
Flags: ro - READ-ONLY
Columns: IRQ, USERS, CPU, ACTIVE-CPU, COUNT
 #    IRQ  USERS          CPU   ACTIVE-CPU      COUNT

If I was a conspiracy theorist, I would say that the latest firmwares cause a drop in throughput as motivation to get the hapax2 LOL.
