I have been using RB951G-2HnD/RB751U-2HnD with great success...
It really great device.
I'm using it primary for vpn/firewall/QoS. I notice that the CPU is hitting 100% and I understand that I probably hit the limit of those devices - especialy when there is alot incoming connection then the dropping start to trigger and basically without limiting connection number per that one ip router is having the worst time of his live.
Also with the configuration I'm using on 250/25 internet I'm getting 100/25 - after disabling firewall/qos/vpn im seeing 130/25 and cpu is still in his high 90% ( even after overclocking to 700MHz)
I'm looking for a replacement, I found RB750GR3 (its a dual core 880MHz cpu which is a big boost from 600MHz single core) but it looks like its very fast with firewall/qos disable and same slow with both enabled (https://mikrotik.com/product/RB750Gr3#fndtn-testresults) which is something strange to be honest for dual core that is faster but looking on same results for RB951 (https://mikrotik.com/product/RB951G-2Hn ... estresults) yell conclusion that I'm not seeing something (or don't know how to read it) - but looking at scheme for those cores it looks like 1 handle ports 1,3,5 and other does 2,4.
I don't mind loosing WiFi (because I will continue to use my ap router as wifi access point) I just want to improve download speed for everything that is connected by cable.
Will RB750GR3 handle 250 Mbps with firewall/qos or should I look on something with bigger budget ? Or are there any other recommendations ?
