I'm trying to recv files via DPDK TCP sock.
I found that DPDK ANS is faster at low size file but slower at big size than kernel, as below.

I just wonder if It is a known issue.
I tried some settings to optimize performance(cpu affinity, pinning, numa, tcp_nodelay, change BURST_TX_DRAIN_US, MAX_TX_BURST and etc...) but these make no difference.
