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!
