Hi,

I’m trying to use dpdk-te= stpmd TX-ONLY mode as traffic generator for performance test.

With command like below, the te= stpmd is sending traffic in quit high rate.

Is there some way to configure = the generated packet rate?

I tried to set txtimes (set txt= imes 1000,1000), but it seems no effect on packet rate.

Also do we have some way to sho= w current packet rate in testpmd?

Thank you.
