Depending on the architecture of your network, you can balance the traffic
of multiple VLANs across different links by setting the root bridge to
opposite switches.
So if you have an access layer switch feeding into say 2 catalyst L3
switches, you can set the root bridge for VLAN2 to the first Catalyst and
for VLAN3 to the second Catalyst. This will allow you to use bandwidth from
both links. This is one of the benefits of PerVLAN Spanning Tree versus a
Common Spanning Tree.
