Looks like a definite improvement. I hope the fix works long term for you.
I've been shuffled onto different SVLANs several times in an effort to avoid congestion and the problems for me always return. I'm on BT Wholesale back-haul and my particular problem has been blamed on BT Wholesale continually overloading their SVLANs. Its been a never ending battle to maintain a decent connection, a huge waste of time and effort.
