I have an RB433 AH routerboard... My internet connection speed provide 100mbps.
But I speedtest 40mbps show.
The fastrack enabled, not better when turn off any firewall rules (without the fasttrack).
I use the eth1 for the ISP. The Ip Settings IPv4 Fasttrack Active but Bytes Packet 0.
In theFilter rules fasttrack connection show the Bytes for the trafic. But the 'special dummy rule to show fasttrack counter' 0...

According to the test results this board can reach 192.5 Mbps https://mikrotik.com/product/RB433AH#fndtn-testresults... So that is not the case...!
However,
Requirements
IPv4 FastTrack is active if following conditions are met:

no mesh, metarouter interface configuration;
sniffer, torch and traffic generator is not running;
/tool mac-scan is not actively used;
/tool ip-scan is not actively used;
FastPath and Route cache is enabled under IP/Settings

Make sure you meet the above requirements... Also you could post your firewall rules configuration...

bematft , i have rb433ah too with 2 ar9223 wifi cards . My ISP gives me 100/100mb/ps pppoe client . I achieve real 95/95 with 80-85% cpu load with fasttracking enabled over lan ethernet . Over wifi the load increase much more - same load only ~60mb/ps .

Thanks Guys,

I think My ISP is gone bad. At the easter fesitvs it worked around 70-80Mbps...
Unfortunately I ordered a MikroTik RB2011iL-IN.... Looks like the problem is not with the 433 (without Gigabit Eth)

Various ISP have problem with the network load since many are home due to corona.

2011 instead of a 433 is no improvement when it comes to routing capacity. The fact that it has 5 gigabit ports is only relevant for LAN switching, but the CPU power is what matters for routing, and there's the same MIPSBE architecure at 15% less frequency. Cancel the order by all means. If you need better throughput, hAP ac² is the best deal if you can live with just 5 ports like you did until now, less RAM, and no PoE out as compared to the 433.

Cancel the order by all means.

I think I won't be able to... I'll try to sell th 2011.
But thanks for your answer!!

Maybe the shop will accept if you ask them to deliver two hAP ac² instead of one 2011 if they haven't shipped it yet
