First of all i'm sorry for my horrible English.
I have a KVM VPS for my personal VPN. Server running on FreeBSD 11.0-RELEASE-p1 with OpenVPN 2.4.0, and ipfw kernel nat. Direct connection speed between me and VPS ~10-12 Mbps. Via tunnel speed is ~1.6-5 Mbps (which enough for me)
This tunnel is for web surfing. When i download file from server via tunnel everything fine. But when i try to open some web page, speed is 2-7kbps!!
EXCEPT youtube! Youtube always works fast and shows videos in 1080p with no freezes.
I tried different combinations of tcp/udp, cipers, sndbuf/rcvbuf, tun-mtu/mssfix, comp-lzo/compress lz4-v2/no compress, different TAP drivers, Windows 7 64/Ubuntu with no luck.

Can somebody help me to figure out where is the problem ?
Thanks!
