[dpdk-dev] About the comparation of "test-pipeline" and "l2fwd"？

[bai bakari]

Hi,


I tested the performance of "test-pipeline"(--none) and "l2fwd", but the result confused me.
"l2fwd" was three times better than "test-pipeline" in pps. 
I set them to the same parameters like this:


"l2fwd":
MAX_PKT_BURST=64
nb_rxd = 1024
nb_txd = 1024


"test-pipeline"
burst_size_rx_read = 64
burst_size_rx_write = 64
burst_size_worker_read = 64
burst_size_worker_write = 64
burst_size_tx_read = 64
burst_size_tx_write = 64



port_rx_ring_size = 1024
port_tx_ring_size = 1024



ring_rx_size = 1024
ring_tx_size = 1024



Can anyone know this reason and tell me? Thank you in advance.


Best wishes!
