Just had a quick review on AC2 and RB4011 with 7.8b3, and I found a new issue of logging.
Log files would not completely show up all messages such as red warning and blue error sometimes.
BTW, DNS cache problem that cache couldn't be flushed has been fixed since 7.8b3.

Not specific to 7.8b2, but seems to affect it. Starting from v7.7, it seems the dns resolver has a memory leak that eats up all the Mikrotik memory until the RouterOS crash and reboots. Not all are affected, but all affected confirmed to be providing DNS services for client devices. If you're runni...

I'm worried about 2.5G port compatibility.

I loved seeing solid and better throughput on the down whilst doing the up, vs the overbuffered tests. I think this is the correct way to use CAKE. Just need to add CAKE on ether1 for outbound traffic and on ether2 for inbound traffic. cake.png qt.png I can't set CAKE on virtual bridge for download...

I would not consider downgrading to v6.49 because v7 is more functional such as fq_codel for reducing bufferbloat.
BTW, I feel ac2 wireless also has bufferbloat issue.

My experience is that hap ac2 with IPQ-4019@716MHz and 256MB RAM(early bonus version) can't handle 500M/250M FTTH PPPoE clent without Fasttrack. Although the ac2's temperature is ok, it is high loading about ~99% without Fasttrack on RouterOS v7 during wired(cat.6) full speed test. High CPU loading ...

Mikrotik didn't say anything about RAM type.
IPQ6010 supports DDR3L and DDR4.

Chateau LTE18 ax and Chateau 5G ax datasheets show RAM type DDR3L


so now i say

will be nice to see an hap ax3 with cpu at 1.800 mhz and DDR4

I agree with u....and another rb450gx4 mark ii

the only tests where ax2 surpass ac2 is on fast-path probably because switch to CPU link now supports more bandwidth improving from 2-gbit to 2.5-gbit the other test show very similar performance with the expected penalties from comparing Ros 6.x Vs Ros 7.x surely when comparing ax2 to ac2 both on ...

Hi, I think I have found something interesting here, a QoS script compatibel w Fasttrack: https://forum.mikrotik.com/viewtopic.php?t=113308 I tried it, by adding a new dedicated Internet bridge, but failed.... Time is over for my experiments, but I will try again next time. Edit: I tried adding a s...

New performance test result is so much better now for AX2, thank you Mikrotik!

It gets better, but it's not much faster than IPQ-4018/4019.

cumulative advantage of Chateau 5G ax over hap ax2 is between 25% - 40%

will be nice to see an hap ax3 with cpu at 1.800 mhz

Mikrotik just updated hAP ax² and Chateau 5G ax performance results. What I've noticed is that they both have IPQ-6010 + 1G RAM(DDR3L or DDR4?) + 128M NAND. IPQ-6010 on Chateau 5G ax is running at auto (864-1800) MHz , but it's running at 864 MHz on hAP ax². https://mikrotik.com/product/hap_ax2#fndt...

I would believe Mikrotik wants to lock hardware performance for pricing.
Particularly cpu overclocking.

I guess that Mikrotk want to do some product segmentation if it is not a firmware bug.
