Hello!
Well skb recycling is "research" and should be used to challange to vm/slab
people to start with... And I guess you will get objections about the extra
stats as well.
I see you increased the RX-ring to 1024 pkts.
Did you really see any improvement with this?
Also I would be interested if you have any numbers for recycling patch?
Jamal and I spent some days after OLS to test and tune but it wasn't to
promising at that time but it's reworked now.
Cheers.
