[dpdk-dev] how to find transfer rate ?

[Nulik Nol]

Hi all,
I finally bought my Intel NIC (an I340-T2,
E1000_DEV_ID_82580_COPPER_DUAL, dev id 0x150E) and ran the dpdk with
success. But when testing the cards for speed rate with "testpmd"
program provided in the distribution I can't find the Packets Per
Second rate, the statistics reported do not show start and end time,
so I can't calculate how much packets were transferred. How do you get
this value ?

Thanks in advance
Nulik

Hi Nulik,

The "testpmd" application is not intended to supply this kind of 
information, and more globally to behave as a Traffic Generator.
It has been intentionally designed to forward received packets using 
pre-configured port relationships, and it was assumed that all network 
traffic variables (packet size, throughput, test duration) would be 
performed by true Traffic Generators such as IXIAs for instance.

Best regards,
Ivan
