Ring-ping

Ring ping is a DPDK application to measure CPU latency.

Instalation

Requires DPDK from https://dpdk.org

Build:

export RTE_SDK={path to DPDK}
export RTE_TARGET=build
make

Usage

Since this does not use any actual hardware, it can be run as non-root. The DPDK arguments tell it to use 2 cores and not use huge pages or PCI. To run the test for 30 seconds

./build/app/rping -c 3 -n 2 --no-pci --no-huge -- -t 30
