Im using Mikrotik for 2 years. Now I have 500 clients on MikroTik x86 and 200 mbit/s of uplink. Under the load of 50-70 mbits, approximately, i have and my clients have some problems with online video. when I try to watch the video 720 or 1080, sometimes its 480 and it always stops and loading then again. Just at once, I start downloading from any http server and my speed is Ok. Here is my problem in video. http://www.youtube.com/watch?feature=pl ... luoyGOeVHc
What it can be? problems with NAT? but my roiter is about 10% of load. If i descrease the speed in mikrotik till 30 -40 mbits - its ok, and i can conclude youtube servers works Ok.
