Someone else has already commented about asking someone about the 
reboots.  I'll simply mention the "perf" utility and assuming the CPU 
type in your device supports it you could take some profiles to see just 
where the time is being spent.  You can probably guess already that it 
involves vlan processing but it may be helpful to have more of the details.
