What do you mean by this?  Do you mean the link speed?

I don't see this behavior at all.  I just tried running our standard
performance tests (nc_test_slave) on both the new and the old stacks
and for the most part, the new stack gave me more (up to 20%) 

What sort of traffic are you running?
Which platform (the VADS 8260)?
