Performance problems when creating 50+ vlans


Hi All.

I have a problem when i try to create alot of VLANS with the intel proset drivers , when i reach around 60 Windows (2008 R2 SP1) starts to be very slow and unresponsive to the point of its useless. , wmi takes a majority of the processing power.

I tried combinations of different network cards and driver versions and all seems to "break" just after 50 vlans , if i spread the load on more than one adapter its the same.

Have anyone sucessfully created 100vlans (over two or more nics) and still leave a usuable windows running

best regards
