Slow internet

[Chraze]

Hi!

I have a PC with two Realtek Gigabit NICs. My first problem was "watchdog timeout", caused by the network cards driver. But I fixed it when I installed a custom Realtek driver based on FreeBSD 10.3
So, my second problem is the network very slow. I have Gigabit connection. I tested it with OpenWrt and the avarage speed was 800Mb/s. Now the speed is 300-400 Mb/s.

What happens?
