Good day!
Have the following problem, there is a mikrotik rb2011uias-2hnd and two ISP's with static ip connected to ether1 and ether2, ether3 master-port, ether4-5 slave, ether6 master-port, ether7-9 slave, ether3 and ether6 in birdge. When i connecting a PC with gb network card to ether4 speed download speedtest.net 94mb(provider 1 gives 300mb), auto-negotiation is enabled, if i disable this option and force put to 1000mb port is down. When you connect a Gigabit switch, the same story, the speed depends on 100mb. My config: 2 vlan, no wlan, 6 firewall rules, 4 netmap, NAT, 7 mangle rules, i turned off all the rules except nat, nothing has changed. Maximum CPU usage 30-50%.
Any ideas?

fastrack is enabled, os version i tested 6.32, 6.35. Interesting moment i using test other rb2011(null settings) on simple schema isp1-mikrotik-pc and i get 250-270mb

Sounds like a bad cable. (OR a bad port on your mikrotik).
Try putting the ISP cable directly in your computer and see if you get Gbit link.

I connected isp1 to my pc, download speed about 300mb. Cable 5e category, i tried change there, same story. Today i try change port to ether2 and other.

Tried different Gigabit ports, the link also falls. Know I'm not the only one lucky?) Conclusion equipment can not cope. Can you recommend something more productive. Thanks.

I Have same problems with my rb3011 http://forum.mikrotik.com/viewtopic.php?f=3&t=114827

I was not able to overcome this problem. As I realized my network was too many connections. This is a semi-public network, limitations it was impossible to put. I purchase more productive CCR1009-1G-1S
