I post this topic here because mikrotik deleted my detailed comment on youtube under video Router OS 7!

After flashing ROS 7 stable on my home hEX S I faced Up/Down speed drop.
It’s main device in my home gigabit network. Connection to ISP provider is by 1000BASE-T, simple DHCP client. There is no any complex settings on router - it has been used as simple soho router for 2 clients connected mostly by ethernet, rarely by wifi. STP if off to get max hw acceleration, a few simple rules to open port for OVPN server and drop others - plain firewall setup nothing complex.

Being on 6.49 I measured speed by speedtest net app every 3-5 days just for self control to be sure everything fine. And repeat of results was 100% 10/10.
My ISP plan is 500 Mbits, but on start testing with speedtest-net it gives even 900, then shapes slowly to ~600.

All tests were made on PC with wired connection and CLI app speedtest-net on stable version of debian linux.

Here is my usual results on 6.49:
Download: 670.01 Mbps (data used: 318.3 MB)
Upload: 754.98 Mbps (data used: 418.6 MB)

I really was waiting for 7 because want to replace slow OpenVPN with fast Wireguard. And it was a such bummer to see this after update:
7.1 STABLE:
Download: 418.22 Mbps (data used: 204.1 MB)
Upload: 476.46 Mbps (data used: 226.4 MB)

I tried 10 times, then i made factory reset and repeated again: results were the same - not higher than 500.
Then I rolled back to 6.49 and got same results I used to have.

My conclusion: It’s performance regression.
I really like your products, because only you have such amount of small WIRED routers with such functionality.

So, devs, please, fix this! Because keenetic giga product line can offer 990 mbits by NAT and has working wireguard in firmwares.
But they do not have winbox and own CLI, that I like so much in your products.
