Ive have a funny problem, I am using ECMP Load Balancing on 2Wan Port. Internet is super fast, But when I watch any Youtube Clip, It is very slow.

What can it be?

Try using PCC. ECMP has some problems when streaming anything over 10 minutes.

with PCC all my port 443 traffic gets splitted and then gets logged out, which causes a problem

Actually with ECMP you are more likely to have that problem. With PCC your connections get marked and then sent out a route and will continue to go out the same route until the connection is dropped. Where did you see this problem?

In SOuth Africa ABSA online bank could not log in at all with PCC, as soon as I set it On ECMP and Marked all Port 443 traffic to 1 Wan connection, it works perfect,but youtube is super slow. Everything else is fast

Make sure you're using the "both-addresses" option for your PCC rules.

Agreed I think you have something wrong in your PCC. Try it again.

Here is my Mangle Export, Please help mme with my PCC.

IS, Mweb and Mweb2 are my 2 DSL lines connected on the load balancer

Yea that is not right. Follow this step by step.

I changed everything back to PCC and the youtube streaming is still slow, Ive got 3 4Mb lines running at 1Mb each constant, So Ive gor alot of free bandwith per line

What can be the problem?

Could your ISP be throttling you?

No, I see that sometimes it streams fast, and othertimes slow as hell

Try using src-address only in your clasifiers. Works fine in 480 mode.
