Hello!
I studying programming with DPDK SDK . So I write a small app to send/receive packets , now I testing it and see next situation:
iperf3 show  9,4 - 9,7 Gbps on TCP
 
my app can *send* only at 4+Gbps (I see counters in the rte_eth_stats) .  I have tried to speed-up my app by:
-  using 1+ number of TX queues (device claim support 64)
-  increase size of burst from 32 up to 128  
- turn off any offloads related to checksumming
 
No effect.
 
Any recommendation what I'm need to check ?
 
Thanks in advance!
