[dpdk-dev] Performance issue in DPDK setup

We have VMs on a physical server with both VMs having 1 core 7 GB RAM
with DPDK 16.04. The VMs are communicating using SR-IOV (per VM 1 VF is
assigned). We are performance benchmarking the setup with our
application which sends burst of packet on the sender VM and receiver VM
receives it in a ring. But we are unable to get good performance at L2
layer also. The problem we noticed is that if we attempt to send a burst
of 1 lakh (1,00,000) packet at a go, the receiver side is able to
receive only 40,000 packets. We feel there is some buffer overflow
happening but we cannot trace it. So, we feel a uniform rate of sending
packet and not a huge burst would be a better application for benchmarking.
Is there a application available in DPDK where we can specify the
sending rate i.e. ask the application to send 1 Gbps traffic etc, so
that it would send 1 Gb traffic uniformly in the second.
Please guide us on this.
