Both look good to me. For the pp benchmark: Before: Fast path results: no-softirq-page_pool01 Per elem: 11 cycles(tsc) 4.337 ns ptr_ring results: no-softirq-page_pool02 Per elem: 529 cycles(tsc) 196.073 ns slow path results: no-softirq-page_pool03 Per elem: 554 cycles(tsc) 205.195 ns After: Fast path results: no-softirq-page_pool01 Per elem: 11 cycles(tsc) 4.401 ns ptr_ring results: no-softirq-page_pool02 Per elem: 530 cycles(tsc) 196.443 ns slow path results: no-softirq-page_pool03 Per elem: 551 cycles(tsc) 204.287 ns -- Thanks, Mina
